Roesia si Pengkor ([ruˈsia siˈ peŋˈkor]; Perfected Spelling: Rusia si Pengkor, Indonesian for Secret of the Clubfoot), also known as Hadji Saleh, is a 1939 film from the Dutch East Indies (now Indonesia) which was directed and produced by The Teng Chun for his Java Industrial Films.

Starring Da'ing, Bissu, and Hadidjah, this black-and-white film followed a young woman who is saved from deceptive suitors by her beloved and a man known as "Si Pengkor".

Upon his release, after being found not guilty, Saari must fight a would-be suitor named Usin before ultimately being recognised as Suti's husband-to-be.
