Leon Dai (Chinese: 戴立忍; pinyin: Dài Lìrěn; Pe̍h-ōe-jī: Tè Li̍p-jím, born 27 July 1966) is a Taiwanese actor and film director. His film Cannot Live Without You (2009) was Taiwan's submission to the 82nd Academy Awards for Best Foreign Language Film. The film also won two awards at the 46th Golden Horse Film Awards.

In 2016, Dai faced public anger in China over remarks perceived as supportive of the Taiwan independence movement, although he denied any such sympathies. Shooting for the film No Other Love had already been completed; he was fired and his scenes were dropped.
