St. Conleth's College is a private co-educational Catholic school in Ballsbridge, Dublin, founded on 4 September 1939 by Bernard Sheppard.

[2] The school was named after Conleth, (450-519AD), a sixth-century Irish monk who was a moulder of precious metals whose feast day is 4 May.

[citation needed] In November 2017, the Kevin Kelleher Wing was opened, adding a performance room and study area on top of the gymnasium.

[6] St. Conleth's won the Basketball Ireland National Cup and League double in 2009 at the U16 Boys B level.

[8] In 2019, St. Conleth's had two winners in the grand final of the Irish Times Debate, with Kevin Roche (representing the Kings Inns) winning the individual competition and Daniel Gilligan (representing TCD Hist Society) the team competition.
