Kadeem Raymond Mathurin-Harris

Kadeem Harris was 16 years and 201 days old when he made his debut for Wycombe Wanderers on 26 December 2009. That made him the club's youngest player in the Football League. Wycombe were where his career began, and the 2010–11 season brought him the League Two Apprentice of the Year award.

In January 2012 he moved to Cardiff City for an undisclosed fee, reported at between £50,000 and £100,000. He was in the squad that won the Championship in 2012–13 and went up to the Premier League, though he made only one league appearance that season. Loan spells at Brentford and Barnsley followed, and over his time in Wales he played 70 league games and scored six goals. He is a right-footed player who works mainly on the left, as a midfielder or a winger.

Harris joined Sheffield Wednesday on a free transfer in July 2019 and played 81 league games, scoring three. In September 2021 he went abroad, signing for Metalist Kharkiv in Ukraine. He was later loaned to Tuzlaspor, and in July 2022 he signed a two-year deal with Samsunspor. He was in the squad for the first half of 2022–23, when the club won the TFF 1. Lig and went up to the Süper Lig, and he left in early 2023. Bandırmaspor and Şanlıurfaspor came next, both on free transfers.

He returned to English football in November 2024 with a short-term contract at Carlisle United, where he made eight league appearances. In July 2025 he signed for Salford City, again on a free transfer. He played 24 league games there in 2025–26 and scored four goals, before moving on to Gillingham.

He has not won a senior cap.
