Tempting Heart (Chinese: 心動) is a 1999 movie, directed and co-written by Sylvia Chang, starring 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. This song became a radio hit and can still be frequently heard on the radio or at karaoke bars/boxes.

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