Cheech & Chong's The Corsican Brothers is an American film released in 1984, the sixth feature-length film starring the comedy duo Cheech and Chong. Cheech Marin and Tommy Chong star as the two twin brothers in a parody of various film adaptations of the 1844 Alexandre Dumas novella, The Corsican Brothers.

To date, it is the last live-action film starring the duo, and the only one that does not heavily revolve around the normal elements of stoner comedy (being that there are very few references to marijuana). Instead the film elects to be a straightforward farce of swashbuckler films.
