Portishead Town

Originally known St. Peter's Portishead until a name change in 1948, the club played in small regional leagues for years until joining the Somerset County League in 1975. They won the Premier Division title four times in five years between 1993–94 and 1997–98. After their fourth successive runner-up campaign in the 2004–05 season, Portishead successfully applied for promotion to the Western League.

In Portishead's first season of Western League football, they finished in the top half of the table only to better their performance the following season. In 2006–07, Portishead achieved their then-highest ever finish in the history of the club finishing runners-up to Truro City Although Portishead finished as runners-up, they were unable to be promoted to the Western League Premier Division as their ground was not suitable, lacking (at that time) floodlights. The 2023–24 season saw Portishead crowned champions of Western League Division One, an 8–0 thrashing of Gillingham Town securing the title.

The following season, the club spent their first three months in the Premier Division playing games away from home or at neutral venues, as their Bristol Road ground went under total redevelopment, including the installation of an artificial playing surface. They returned home on 16 November, with a 3-0 win over Ilfracombe Town in front of a record-breaking 579 fans. This record would later be broken again, as 1,045 spectators watched them defeat local rivals Clevedon Town on 25 February.

Despite finishing second in the 2025-26 Southern Football League Division One South, which would have enabled them to qualify for the promotion play-offs, the club were instead disqualified from the play-offs and relegated to Step 5 due to ground grading issues.
