Armour of God (Chinese: 龍兄虎弟; Jyutping: Lung4 hing1 fu2 dai6 lit. 'Big Brother Dragon, Little Brother Tiger') is a 1986 Hong Kong action adventure comedy film starring and directed by Jackie Chan, and written by Chan, John Sheppard and Eric Tsang (who also co-directed). It co-stars Alan Tam, Lola Forner, and Rosamund Kwan.

The film combines Chan's martial arts, comedy and stunts with an Indiana Jones style adventure film theme. It is deemed a cult classic. Chan came the closest he had ever been to death in this film during a relatively routine stunt; he leaped onto a tree from a ledge, but the branch he grabbed snapped, sending Chan plummeting and cracking his skull.

The film was the highest-grossing film in Hong Kong at the time, grossing an estimated US$16,300,000 (equivalent to $45,000,000 in 2023) at the box office in Asia and Europe. It was followed by the sequels Armour of God II: Operation Condor in 1991, and CZ12 in 2012.
