The Brisbane Lions is a professional Australian rules football club based in Brisbane, Queensland, that plays in the Australian Football League (AFL).

The club was formed in late 1996 via a merger of the 1883 foundation VFL club the Fitzroy Lions, and the 1987 expansion club the Brisbane Bears. The club's colours of maroon, gold and blue are drawn from both entities. The Lions are the most successful AFL club of the 2000s, appearing in four consecutive Grand Finals from 2001 to 2004 and winning three premierships (2001, 2002, 2003). They play home matches at the Gabba and have their offices and indoor training facilities located within the stadium.
