A Blind Bargain is a 1922 American silent horror film starring Lon Chaney and Raymond McKee, released through Goldwyn Pictures. The film was directed by Wallace Worsley and is based on Barry Pain's 1897 novel The Octave of Claudius. Lon Chaney played a dual role in the film, as both Dr. Lamb and "the Ape Man", one of Chaney's few "true horror films". The claim that Wallace Beery appeared as an ape-man uncredited has never been proven, but does persist in many sources.

Leonidas Frank "Lon" Chaney was an American actor and makeup artist. He is regarded as one of the most versatile and powerful actors of cinema, renowned for his characterizations of tortured, often grotesque and afflicted, characters and for his groundbreaking artistry with makeup. Chaney was known for his starring roles in such silent horror films as The Hunchback of Notre Dame (1923) and The Phantom of the Opera (1925). His ability to transform himself using makeup techniques that he developed earned him the nickname "The Man of a Thousand Faces".
