The NSW Cup, currently known as the Knock-On Effect NSW Cup for sponsorship reasons, is a rugby league competition for clubs in New South Wales. The competition has a history dating back to the NSWRFL's origins in 1908, starting off as a reserve grade competition, and is now the premier open age competition in the state. The New South Wales Cup, along with the Queensland Cup, acts as a feeder competition to the National Rugby League premiership. The competition is the oldest continuous rugby league competition in the Australia.
The NSW Cup is contested by reserve squads of NSW-based NRL teams and also includes sides representing teams that once competed at the first grade level in the NSWRL Premiership but no longer field teams in the NRL competition, and teams that have not fielded teams in the NRL competition. The North Sydney Bears are the only team to have competed in every season, since the start of the competition since 1908.
