Ecstasy (Czech: Extase; French: Extase; German: Ekstase) is a 1933 Czech erotic romantic drama film directed by Gustav Machatý and starring Hedy Lamarr (then Hedy Kiesler), Aribert Mog, and Zvonimir Rogoz. Machatý won the award for Best Director for this film at the 1934 Venice Film Festival.

The film is about a young woman who marries a wealthy but much older man. After abandoning her brief passionless marriage, she meets a young virile engineer who becomes her lover. Ecstasy was filmed in three language versions – German, Czech, and French. It is perhaps the first non-pornographic movie to portray sexual intercourse and the female orgasm, although never showing more than the actors' faces.
