Chevrolet is an American automobile division of the manufacturer General Motors (GM). In North America, Chevrolet produces and sells a wide range of vehicles, from subcompact automobiles to medium-duty commercial trucks. Due to the prominence and name recognition of Chevrolet as one of General Motors' global marques, "Chevrolet" or its affectionate nickname Chevy is used at times as a synonym for General Motors or its products, one example being the GM LS1 engine, commonly known by the name or a variant thereof of its progenitor, the Chevrolet small-block engine.

Louis Chevrolet (1878–1941), Arthur Chevrolet (1884–1946) and ousted General Motors founder William C. Durant (1861–1947) started the company on November 3, 1911 as the Chevrolet Motor Car Company. Durant used the Chevrolet Motor Car Company to acquire a controlling stake in General Motors with a reverse merger occurring on May 2, 1918, and propelled himself back to the GM presidency. After Durant's second ousting in 1919, Alfred Sloan, with his maxim "a car for every purse and purpose", picked the Chevrolet brand to become the volume leader in the General Motors family, selling mainstream vehicles to compete with Henry Ford's Model T in 1919 and overtaking Ford as the best-selling car in the United States by 1929 with the Chevrolet International.

Chevrolet-branded vehicles are sold in most automotive markets worldwide. In Oceania, Chevrolet was represented by Holden Special Vehicles, having returned to the region in 2018 after a 50-year absence with the launching of the Camaro and Silverado pickup truck (HSV was partially and formerly owned by GM subsidiary Holden, which GM retired in 2021). In 2021, General Motors Specialty Vehicles took over the distribution and sales of Chevrolet vehicles in Oceania, starting with the Silverado. In 2005, Chevrolet was relaunched in Europe, primarily selling vehicles built by GM Daewoo of South Korea with the tagline "Daewoo has grown up enough to become Chevrolet", a move rooted in General Motors' attempt to build a global brand around Chevrolet. With the reintroduction of Chevrolet to Europe, GM intended Chevrolet to be a mainstream value brand, while GM's traditional European standard-bearers, Opel of Germany and Vauxhall of the United Kingdom, were to be moved upmarket. However, GM reversed this move in late 2013, announcing that the brand would be withdrawn from Europe from 2016 onward, with the exception of the Camaro and Corvette. Chevrolet vehicles were to continue to be marketed in the CIS states, including Russia. After General Motors fully acquired GM Daewoo in 2011 to create GM Korea, the last usage of the Daewoo automotive brand was discontinued in its native South Korea and succeeded by Chevrolet.

On November 8, 1911, the Chevrolet Motor Car Company was incorporated. It was founded by Swiss race car driver and automotive engineer Louis Chevrolet with his brother Arthur Chevrolet, William C. Durant and investment partners William Little (maker of the Little automobile), former Buick owner James H. Whiting, Edwin R. Campbell (son-in-law of Durant) and in 1912 R. S. McLaughlin CEO of General Motors in Canada. Former Buick officers were also employed, including Curtis R. Hatheway as secretary.

Durant was dismissed from his senior management position at General Motors in 1910, a company that he had founded in 1908. In 1904 he had taken over the Flint Wagon Works and Buick Motor Company of Flint, Michigan. He also incorporated the Mason and Little companies. As head of Buick, Durant had hired Louis Chevrolet to drive Buicks in promotional races. Durant planned to use Chevrolet's reputation as a racer as the foundation for his new automobile company. The first factory location was in Flint, Michigan at the corner of Wilcox and Kearsley Street, now known as "Chevy Commons" at coordinates 43.00863°N 83.70991°W, along the Flint River, across the street from Kettering University.

One of the technical advancements Chevrolet benefited from was the implementation of an overhead valve engine from the very beginning, as the company was developed by the former owner of Buick, which had patented the overhead valve and cross-flow cylinder design as being more efficient than the conventional use of the flathead engine.

Actual design work for the first Chevy, the costly Series C Classic Six, was drawn up by Etienne Planche, following instructions from Louis. The first C prototype was ready months before Chevrolet was actually incorporated. However, the first actual production was not until the 1913 model. So in essence there were no 1911 or 1912 production models, only one pre-production model was made and fine tuned throughout the early part of 1912. Then in the fall of that year the new 1913 model was introduced at the New York auto show.

Chevrolet first used the "bowtie emblem" logo in 1914 on the H series models (Royal Mail and Baby Grand) and The L Series Model (Light Six). It may have been designed from wallpaper Durant once saw in a French hotel room. More recent research by historian Ken Kaufmann presents a case that the logo is based on a logo of the "Coalettes" coal company. An example of this logo as it appeared in an advertisement for Coalettes appeared in the Atlanta Constitution on November 12, 1911. Others claim that the design was a stylized Swiss cross, in tribute to Chevrolet's home country. Over time, Chevrolet used several different iterations of the bowtie logo at the same time, often using blue for passenger cars, gold for trucks, and an outline (often in red) for cars that had performance packages. Chevrolet eventually unified all vehicle models with the gold bowtie in 2004, for both brand cohesion as well as to differentiate itself from Ford (with its blue oval logo) and Dodge (who has often used red for its imaging), its two primary domestic rivals.

Louis Chevrolet had differences with Durant over design and in 1914 sold Durant his share in the company. By 1916, Chevrolet was profitable enough with successful sales of the cheaper Series 490 to allow Durant to repurchase a controlling interest in General Motors. After the deal was completed in 1918, Durant became president of General Motors, and Chevrolet was merged into GM as a separate division. In 1919, Chevrolet's factories were located at Flint, Michigan; branch assembly locations were sited in Tarrytown, N.Y., Norwood, Ohio, St. Louis, Missouri, Oakland, California, Ft. Worth, Texas, and Oshawa, Ontario General Motors of Canada Limited. McLaughlin's were given GM Corporation stock for the proprietorship of their Company article September 23, 1933 Financial Post page 9. In the 1918 model year, Chevrolet introduced the Series D, a V8-powered model in four-passenger roadster and five-passenger tourer models. Sales were poor and it was dropped in 1919.

Beginning also in 1919, GMC commercial grade trucks were rebranded as Chevrolet, and using the same chassis of Chevrolet passenger cars and building light-duty trucks, sharing an almost identical appearance with GMC products. Until 1921, Chevrolet Corporate headquarters were located at 57th and Broadway in New York City until April when the office was relocated to the General Motors Building at Cadillac Place in Detroit. In January 1921 a General Motors management survey recommended that the Chevrolet Division be cancelled, but Alfred P. Sloan Jr. recommended that the division be saved and William S. Knudsen, a former Ford employee who oversaw production of the Model T, was made Vice President of Operations and performance improved In May 1925 the Chevrolet Export Boxing plant at Bloomfield, New Jersey was repurposed from a previous owner where Knock-down kits for Chevrolet, Oakland, Oldsmobile, Buick and Cadillac passenger cars, and both Chevrolet and G. M. C. truck parts are crated and shipped by railroad to the docks at Weehawken, New Jersey for overseas GM assembly factories.

Chevrolet continued into the 1920s, 1930s, and 1940s competing with Ford, and after the Chrysler Corporation formed Plymouth in 1928, Plymouth, Ford, and Chevrolet were known as the "Low-priced three". In 1929 they introduced the famous "Stovebolt" overhead-valve inline six-cylinder engine, giving Chevrolet a marketing edge over Ford, which was still offering a lone flathead four ("A Six at the price of a Four"). In 1933 Chevrolet launched the Standard Six, which was advertised in the United States as the cheapest six-cylinder car on sale. During the Great Depression the Chevrolet Master introduced a streamlined appearance, showing Art Deco influences and before and after the World War II era, the Chevrolet Deluxe and Chevrolet Fleetline found many buyers.

Chevrolet had a great influence on the American automobile market during the 1950s and 1960s. In 1953 it produced the Corvette, a two-seater sports car with a fiberglass body. In 1957 Chevy introduced its first fuel injected engine,[22] the Rochester Ramjet option on Corvette and Chevrolet Bel Air passenger cars, priced at $484 ($5,419 today). In 1960 Chevrolet joined the newly popular "compact car" market by introducing the Corvair, with a rear-mounted air-cooled engine. In 1963 one out of every ten cars sold in the United States was a Chevrolet.

During the 1960s and early 1970s, the standard Chevrolet, particularly the deluxe Chevrolet Impala series, became one of the United States' best-selling lines of automobiles in history. During that era, the mid-sized Chevrolet Chevelle which was used to introduce the Chevrolet Monte Carlo, and the economically priced Chevrolet Nova, which was the basis for the Chevrolet Camaro, all were commercially successful and included family sedans, practical station wagons, and sporty coupes and convertibles. As the popularity of small, fuel efficient imported vehicles began to find buyers in the US during the 1970s and 1980s, the Chevrolet Vega was introduced while the Chevrolet Chevette was the result of international collaboration. By the mid-1980s, the Vega was gone and the Chevette was about to be discontinued.

Lacking a line of competitive small cars, Chevrolet imported several Japanese models and re-badged them as Chevrolets. The Suzuki-sourced Chevrolet Sprint and the Isuzu-supplied Chevrolet Spectrum were a better match to compete against the popular Toyota Corolla and Honda Civic. The Chevrolet Citation was the division's first compact sized front-wheel-drive car along with the Chevrolet Cavalier, followed up by the Chevrolet Celebrity. Chevrolet during the 1990s formed a partnership with Toyota and introduced the Geo Prizm while also offering the domestically produced Chevrolet Corsica. As mid-sized family sedans began to gain popularity, the Chevrolet Lumina found many buyers and as minivans began to find buyers, the Chevrolet Venture followed the popular selling Chevrolet Trailblazer and Chevrolet Traverse SUV's.

The basic Chevrolet small-block V8 design has remained in continuous production since its debut in 1955, longer than any other mass-produced engine in the world, although current versions share few if any parts interchangeable with the original. Descendants of the basic small-block OHV V8 design platform in production today have been much modified with advances such as aluminium block and heads, electronic engine management, and sequential port fuel injection. Depending on the vehicle type, Chevrolet V8s are built in displacements from 4.3 to 9.4 litres with outputs ranging from 111 horsepower (83 kW) to 994 horsepower (741 kW) as installed at the factory. The engine design has also been used over the years in GM products built and sold under the Pontiac, Oldsmobile, Buick, Hummer, Opel (Germany), and Holden (Australia) nameplates.

In 2000, Chevrolet brought back the iconic Impala, although unlike its predecessors, this car was a mid-sized front-wheel drive four door sedan. It was produced until 2020, and the last generation (2014-2020) was larger and classified as a full-size passenger car. In 2005, General Motors re-launched the Chevrolet marque in Europe, using rebadged versions of the Daewoo cars produced by GM Korea.

The Chevrolet division largely recovered from the economic downturn of 2007–2010 through launching new vehicles and improving existing lines. GM began developing more fuel efficient cars and trucks to compete with foreign automakers. In late 2010 General Motors began production of the plug-in hybrid Chevrolet Volt, sold as the Opel/Vauxhall Ampera in Europe, which received multiple awards including the 2012 North American Car of the Year, European Car of the Year, and World Green Car of the Year. The Volt/Ampera family was the world's best selling plug-in electric car in 2012 with 31,400 units sold. The Opel/Vauxhall Ampera was Europe's top selling plug-in electric car in 2012 with 5,268 units, representing a market share of 21.5% of the region's plug-in electric passenger car segment. Combined global Volt/Ampera sales passed the 100,000 unit milestone in October 2015. As of June 2016, the Volt family of vehicles ranks as the world's all-time top selling plug-in hybrid, and it is also the third-best-selling plug-in electric car ever, after the Nissan Leaf and the Tesla Model S. Volt sales in the American market passed the 100,000 milestone in July 2016.

In October 2016, GM began production of the Chevrolet Bolt EV, the first ever affordable mass market all-electric car with a range over 200 mi (320 km). The Chevrolet Bolt won several awards including the 2017 Motor Trend Car of the Year award, the 2017 AutoGuide.com Reader's Choice Green Car of the Year, Green Car Reports Best Car To Buy 2017, Green Car Journal's 2017 Green Car of the Year, and was listed in Time magazine's Best 25 Inventions of the Year of 2016.

On February 14, 2021, Chevrolet unveiled the 2022 Bolt EUV and redesigned Bolt EV
