The 56th annual Venice International Film Festival was held between 1 and 11 September 1999.

The Golden Lion is the highest prize given to a film at the Venice Film Festival. The prize was introduced in 1949 by the organizing committee and is now regarded as one of the film industry's most prestigious and distinguished prizes. In 1970, a second Golden Lion was introduced; this is an honorary award for people who have made an important contribution to cinema.
