The A-League Men Grand Final is an association football match to determine the champions for an A-League Men season. Played at the end of the finals series, the game has been held annually since 2006.

Primarily in Australian sports, a grand final is a game that decides a sports league's premiership winning team, i.e. the conclusive game of a finals series. Synonymous with a championship game in North American sports, grand finals have become a significant part of Australian culture. The earliest leagues to feature a grand final were in Australian rules football, followed soon after by rugby league. Currently the largest grand finals are in the Australian Football League (AFL) and National Rugby League (NRL). Their popularity influenced other competitions such as soccer's A-League Men and A-League Women, the National Basketball League, Suncorp Super Netball and European rugby league's Super League to adopt grand finals as well. Most grand finals involve a prestigious award for the player voted best on field.
