EFL League One was created in 2004 after a renaming of the lower leagues in English football. Since the start of the newly re-branded league many players have scored a hat-trick. Hector Sam then playing for Wrexham has the distinction of being the first player to accomplish this on 10 August 2004.
The list includes only hat-tricks scored in the league; hat-tricks scored in play-off matches are not counted.
