The Canterbury Bulldogs are an Australian professional rugby league football club based in Belmore, a suburb in the Canterbury-Bankstown region of Sydney. They compete in the National Rugby League (NRL) premiership, as well as the New South Wales Rugby League junior competitions.
The club was admitted to the New South Wales Rugby Football League premiership, predecessor of the current NRL competition, in 1935. They won their first premiership in their fourth year of competition with another soon after, and after spending the 1950s and most of the 1960s on the lower rungs went through a very strong period in the 1980s, winning four premierships in that decade.
