The Brisbane Broncos are an Australian professional rugby league club based in the city of Brisbane. The Broncos play in Australasia's elite competition, the National Rugby League premiership. The Broncos have won six premierships during their twenty years in competition, making them the league's most successful club.
The club was founded in 1988 as part of the New South Wales Rugby League premiership's national expansion, becoming, along with the Gold Coast-Tweed Giants, one of Queensland's first two participants in the Winfield Cup. The Broncos later played a significant role in the Super League war of the mid-1990s before continuing to compete successfully in the reunified National Rugby League competition of today.
