Margaret Pellegrini (September 23, 1923 – August 7, 2013) was an American actress and one of the last three surviving munchkins from the 1939 film The Wizard of Oz,[2][3]the other two being Jerry Maren and Ruth Robinson Duccini, making Pellegrini one of only two surviving female Munchkins from the film. She was born Margaret Williams inTuscumbia, Alabama. When she was helping a relative in a potato chip booth at the Tennessee State Fair, a group of little people came by and asked if she wanted to join their show, Henry Kramer's Midgets. "At that time I didn't think I was a midget," says Pellegrini (who then stood about 3 ft. 4 inches).

In the film, Pellegrini played a "sleepyhead" and Munchkin villager. After the film, she married Willie Pellegrini (an average-sized ex-fighter) and had two children.

Through the years, Pellegrini had frequently accompanied surviving Munchkins of Oz festivities. In November 2011, she was described as a widowed great-grandmother living in Glendale, Arizona, with a room in her house devoted to her treasured Oz collectibles.
