The Fletcher Cup (formerly known as the FootballSouth Championship) is a New Zealand association football league competition administered by Southern Football involving clubs from the lower half of the South Island of New Zealand. All seven of the teams in the competition in 2025 with the exception of Mosgiel AFC — are from Dunedin, with several of them being second teams from clubs in higher divisions. The league sits at level 4 of the New Zealand football pyramid.
The winner of each season's league, if eligible, enters a playoff series with the winners of the Donald Gray Memorial Cup (Southland) and South Canterbury Division 1 (South Canterbury) for promotion into the Southern Premier League.
