The South Sydney Rabbitohs are a professional Australian rugby league club based in Redfern, a suburb of inner-southern Sydney, New South Wales. They participate in the National Rugby League (NRL) premiership and are one of nine existing teams from the state capital, Sydney. They are often called Souths or The Bunnies.

The club was formed in 1908, as one of the founding members of the New South Wales Rugby Football League, making them one of Australia's oldest rugby league teams. The Rabbitohs were formed, under their original 1908 articles of association, with the NSWRL competition, to represent the Sydney municipalities of Redfern, Alexandria, Zetland, Waterloo, Mascot and Botany. They are one of only two NSW foundation clubs still present in the NRL, the other being the Sydney Roosters.
