The 1922–23 season was the 25th in the history of the Southern League. The league was split into two sections for a third season in a row, one for English clubs and one for Welsh clubs.[1] Bristol City reserves won the English section, whilst Ebbw Vale won the Welsh section. Ebbw Vale were declared Southern League champions after beating Bristol City reserves 2–1 in a championship play-off. Boscombe, Pontypridd and Torquay United were the only Southern League clubs to apply for election to the Football League, with Boscombe being successful.[2] The club was renamed Bournemouth & Boscombe Athletic the following year.
Following to the mid-season resignation of four clubs in the Welsh section due to financial problems and Porth Athletic leaving the league at the end of the season, the following season saw the English section renamed the Eastern Division and the Welsh section renamed the Western Division, with eight clubs transferring from the English section to the Western section.
