Harrison Thomas Clarke (born 2 March 2001) is an English professional footballer who plays as a right-back for Sheffield United on loan from Premier League club Ipswich Town.

[14][15] Clarke missed several weeks due to injury, and made his debut (and scored) on 2 April in a 1–1 draw with Dundee United.

[16] The loan had been due to run for 18 months, but Arsenal exercised a break clause in the deal during June 2022.

[18][19] Clarke made 20 appearances for Stoke, scoring twice against Blackpool and Burnley before being recalled by Arsenal in January 2023.

[3][21] During Ipswich's 4–3 loss to Brentford in October 2024, Clarke became only the second player since Jan Bednarek in February 2021 in Premier League history to score an own goal, concede a penalty and receive a red card in the same game.
