Portland United

Weymouth had a professional club already established when a meeting held on 7 June 1920 set Portland's own side in motion. What followed was mostly local rather than national: two Western Football League Division Two titles in the early 1930s, then decades in which the Dorset Premier League became almost a fixture, won seven times between 1970 and 2014. The club reached the Fourth Qualifying Round of the FA Cup on several occasions from the late 1920s through the 1960s.

Promotion arrived more recently than the honours list might suggest. Back-to-back titles in the Wessex League — Division One in 2015–16, the Premier Division the year after — lifted Portland into the Southern League Division One South. Among those who passed through, Jimmy Dailey stands out: a Scottish forward who had played for Sheffield Wednesday and Birmingham City before taking charge at Portland.

The rivalry with Weymouth carries no trophy or nickname of its own, just the sharpened edge that comes from two clubs sharing a small stretch of coastline. Quarry expansion pushed Portland off their original Grove Corner ground in 1994; they settled nearby at what became New Grove Corner, later renamed Camp & Satherley Stadium. It holds 1,500, with room for perhaps 200 under cover across two stands and the rest standing on grass banking above the pitch.
