The Lost Woman (Spanish: La mujer perdida) is a 1966 drama film directed by Tulio Demicheli and starring Sara Montiel, Giancarlo Del Duca and Massimo Serato.

Sara Fernán escapes from the poor fishing village of her childhood and finds work in a flamenco tavern, a tablao.

One day Rafael, a politician with connections, hears her and is so impressed with her performance that he decides to help her advance her musical career.

To avoid complicating Rafael's political career, she embarks on a grand tour of Europe.

Created to the greater glory of Sara Montiel, the film was a joint Spanish, French, and Italian production.
