Swansea City Association Football Club Under-23s is the most senior team of Swansea City's youth teams and are the club's former reserve team. They compete in the Professional Development League. The Under-23s play the majority of their home fixtures at the club's Youth Academy in Landore, with occasional fixtures taking place at the Liberty Stadium.
The Under-23 team is effectively Swansea City's second-string side, but is limited to three outfield players and one goalkeeper over the age of 23 per game following the introduction of new regulations from the 2016–17 season.
Jon Grey is the interim coach for the Under-23s.
