Tempting Heart (Chinese: 心動) is a 1999 Hong Kong romantic drama film directed and co-written by Sylvia Chang. It stars Takeshi Kaneshiro and Gigi Leung as a pair of onscreen lovers. The film has a notable theme song "Xin Dong", performed by Shino Lin Xiao Pei, which became a radio hit and can still be frequently heard on the radio or at karaoke bars/boxes.

The success of Tempting Heart prompted director Johnnie To to cast Kaneshiro and Leung in his 2003 film Turn Left Turn Right.
