The Legend of Lylah Clare is a 1968 American drama film released by Metro-Goldwyn-Mayer and directed by Robert Aldrich. The film stars Peter Finch, Kim Novak (in multiple roles), Ernest Borgnine, Michael Murphy, and Valentina Cortese. The film was based on a 1963 DuPont Show of the Week TV drama of the same name co-written by Wild in the Streets creator Robert Thom.

A satire on Hollywood, full of references to similar films, it recounts how an untalented beginner is hired to play the legendary Lylah Clare, a tempestuous actress who died mysteriously 20 years ago, and is herself consumed by the system. Although Aldrich's previous 1960s efforts were praised by critics, Lylah Clare opened to negative reviews.
