The 2022–23 English football winter transfer window ran from 1 January to 31 January 2023.
Players without a club may be signed at any time, clubs may sign players on loan dependent on their league's regulations, and clubs may sign a goalkeeper on an emergency loan if they have no registered senior goalkeeper available.
This list includes transfers featuring at least one club from either the Premier League or the EFL that were completed after the end of the summer 2022 transfer window on 1 September 2022 and before the end of the 2023 winter window.
All players and clubs without a flag are English.
While Cardiff City, Swansea City and Newport County are affiliated with the Football Association of Wales and thus take the Welsh flag, they play in the Championship and League Two respectively, and so their transfers are included here.
