The 1912–13 season was the first season in which Swansea Town (now known as Swansea City) took part in league and cup football. The club was elected to Division Two of the Southern Football League. Swansea's first official match was played on 7 September 1912 against local rivals Cardiff City at the Vetch Field. All of Swansea's home games for the 1912–13 season were played on a 'Clinker pitch'. After a 24 game season the club finished third, narrowly missing out on promotion. The club also entered the Welsh Cup and won it at the first attempt, beating Pontypridd 1–0 in a re-played final.
