I Was an Adventuress is a 1940 American drama film directed by Gregory Ratoff, starring Vera Zorina, Richard Greene, Erich von Stroheim, and Peter Lorre. An actress/ballerina works as decoy for two international con artists.

Vera Zorina, born Eva Brigitta Hartwig, was a Norwegian ballerina, theatre and film actress, and choreographer. Today, she is chiefly remembered for her films choreographed by her then-husband George Balanchine. They include the Slaughter on Tenth Avenue sequence from On Your Toes, The Goldwyn Follies, I Was an Adventuress with Erich Von Stroheim and Peter Lorre, Louisiana Purchase with Bob Hope, and dancing to "That Old Black Magic" in Paramount Pictures' Star Spangled Rhythm.
