The Lucky Lady is a 1926 American silent romance film produced by Famous Players–Lasky, distributed by Paramount Pictures, directed by Raoul Walsh, and starring Greta Nissen, Lionel Barrymore, William Collier, Jr., and Marc McDermott.

Plot
As described in a film magazine review, this is a tale of a beauty who lavished her charms upon one man for revenge and upon another for love. It happens in a mythical kingdom where a lovely princess is chafing against the restraint of a convent. She sneaks away, meets a young American man, flirts with him, and falls in love. At the same time, she poses as an alluring vampire and flirts with the wild-living nobleman whom she is supposed to marry but does not love. The prime minister, fearing for the marriage plans of the nobleman and the princess, banishes the young American and the vampire, who is really the princess. The two journey to America and live happily ever afterwards.

Preservation
Contrary to some sources, The Lucky Lady is not a lost film. A print survives in the Library of Congress.
