Cathal McCarthy, born on 31 August 2006 (age 20), is a Republic of Ireland central defender whose senior profile is built around Kilmarnock. Wearing number 4, he has been used in the middle of defence, with his Kilmarnock spell accounting for the substance of his first-team record.
In 2026-27, McCarthy has made 10 league appearances and scored one goal for Killie, while also featuring once in the League Cup. That leaves him on 11 appearances and one goal for the club across all competitions – a modest but clear start to a career presently shaped by Rugby Park.
