Isadora (also known as The Loves of Isadora) is a 1968 biographical drama film directed by Karel Reisz from a screenplay written by Melvyn Bragg, Margaret Drabble, and Clive Exton adapted from the books My Life by Isadora Duncan and Isadora, an Intimate Portrait by Sewell Stokes. The film follows the life of American pioneering modern contemporary dance artist and choreographer Isadora Duncan, who performed to great acclaim throughout the US and Europe during the 19th century. A co-production between the United Kingdom and France, it stars Vanessa Redgrave as Duncan and also features James Fox, Jason Robards, and John Fraser in supporting roles.

Isadora was in the main competition at the 1969 Cannes Film Festival where Redgrave won the Best Actress Prize. The film's initial limited theatrical release on 18 December 1968 by Universal Pictures in Los Angeles was for the Academy Award qualification. Its general release in Spring 1969 received generally positive reviews with major acclaim for Redgrave's performance. However the film underperformed at the box office grossing mere $1.25 million on a $1.7 million budget. For her performance, Redgrave won the National Society of Film Critics Award for Best Actress, and received nominations for the Academy Award for Best Actress and the Golden Globe Award for Best Actress in a Motion Picture – Drama.
