The Queensland Cup, currently known as the Hostplus Cup for sponsorship reasons, is the highest-level regional rugby league football competition in Queensland, Australia. It is run by the Queensland Rugby League (QRL) and is contested by fifteen teams, thirteen of which are based in Queensland, with one based in New South Wales and one in Central Province, Papua New Guinea.

The competition is the present-day embodiment of Queensland's top-level club competition. It replaced the Winfield State League in 1996 and accompanied the Brisbane Rugby League, before becoming the premier competition in 1998, following the disbanding of the Brisbane Rugby League.

Since its inaugural season in 1922, the Brisbane Rugby League was the premier competition in the state of Queensland. Like its counterpart, the Sydney Rugby Football League, the Brisbane Rugby League was thriving, boasting big crowds and large, loyal supporter bases with their respective clubs. The clubs were constant, with new teams rarely entering the competition. However, in 1956, when poker machines ("pokies") were introduced in New South Wales but not in Queensland, Sydney's clubs were able to recruit the best players from Brisbane, Rugby Union and overseas. Within the space of several years, the Sydney Rugby League had come to dominate the code within Australia.

In the 1980s, the NSWRFL began to further expand and supersede the Brisbane competition in popularity and media coverage. In 1982, the first clubs based outside of Sydney, the Canberra Raiders and Illawarra Steelers, were admitted. In 1988, two Queensland-based sides, the Brisbane Broncos and Gold Coast Giants, along with the Newcastle Knights, another team from regional New South Wales, were formed and gained entry into the competition. The Broncos would sign Brisbane Rugby League stars like Wally Lewis, Gene Miles and Allan Langer. In the space of one season, media coverage and match attendance for the Brisbane Rugby League dropped significantly.

In 1996, the Queensland Cup was formed, replacing the Winfield State League, as new federal government laws banned cigarette companies from sponsoring sport. Originally branded the Channel Nine Cup, the 15 round regular season competition featured sixteen teams, fifteen from Queensland and one from Papua New Guinea. The Toowoomba Clydesdales were crowned the inaugural premiers, defeating the Redcliffe Dolphins in the Grand Final. In 1997, three teams withdrew from the competition and the Burleigh Bears joined, becoming the first Gold Coast-based side.

In 1998, the competition became the top level of rugby league in the state, following the end of the Brisbane Rugby League. Channel Nine also ended their sponsorship for the 1998 season, with competition going under name, the Queensland Cup. A sixteen-team competition returned in 1998, with the Bundaberg Grizzlies rejoining and the Gold Coast Vikings being formed.

In 1999, the Grizzlies and Vikings both left the competition, as well as inaugural club Brisbane Brothers and the Townsville Stingers, who played just one season.

In 2000, Bundaberg Rum began a two-year sponsorship of the competition and it was known as the Bundy Gold Cup. The 2000 season was also the first in which all twelve teams remained from the season prior. It would not last long though, as the Cairns Cyclones folded after the 2000 season, leaving no north Queensland representation in the competition. In 2002, the North Queensland Young Guns, a Townsville-based North Queensland Cowboys feeder club, were admitted into the competition. At the end of the 2002 season, the Logan Scorpions, an inaugural club, left the competition.
