Elizabeth "Lee" Miller, Lady Penrose (April 23, 1907 – July 21, 1977), was an American photographer and photojournalist.

Miller was a fashion model in New York City in the 1920s before going to Paris, becoming a fashion and fine-art photographer there.

During World War II, she was a war correspondent for Vogue, covering events such as the London Blitz, the liberation of Paris, and the concentration camps at Buchenwald and Dachau. Her reputation as an artist in her own right is due mostly to her son's discovery and promotion of her work as a fashion and war photographer.

Miller's father introduced her and her brothers to photography at an early age. She was his model – he took many stereoscopic photographs of his nude teenage daughter – and showed her technical aspects of the art. At 19 she nearly stepped in front of a car on a Manhattan street but was prevented by Condé Nast, the publisher of Vogue. This incident helped launch her modeling career; she appeared in a blue hat and pearls in a drawing by George Lepape on the cover of Vogue on March 15, 1927. Miller's look was what Vogue's then editor-in-chief Edna Woolman Chase was looking for to represent the emerging idea of the "modern girl."

For the next two years, Miller was one of the most sought-after models in New York, photographed by leading fashion photographers, including Edward Steichen, Arnold Genthe, Nickolas Muray, and George Hoyningen-Huene. Kotex used a photograph of Miller by Steichen to advertise their menstrual pads without her knowledge. She was hired by a fashion designer in 1929 to make drawings of fashion details in Renaissance paintings but, in time, grew tired of this and found photography more efficient.
