Kieran Tierney (born 5 June 1997) is a Scottish professional footballer who plays as a left-back for Scottish Premiership club Celtic and the Scotland national team.

After six years with Arsenal, including one on loan with La Liga club Real Sociedad, Tierney returned to Celtic in June 2025.

Tierney made his Scotland international debut in March 2016, and has since made more than 50 appearances for the senior side.
