Pegeen Vail Guggenheim (August 18, 1925 – March 1, 1967) was a Swiss-born American painter.
Her painting combines two different artistic styles: surrealism and naïve art.
She was the daughter of the art collector Peggy Guggenheim and the writer Laurence Vail, and the granddaughter of Benjamin Guggenheim, who died on the RMS Titanic in 1912.
