This is a list of English football transfers for the 2004-05 season. Only moves featuring at least one Premier League or First Division club are listed.
The winter transfer window opened on 1 January 2005, although a few transfers took place prior to that date. Players without a club may join one at any time, either during or in between transfer windows. Clubs below Premier League level may also sign players on loan at any time. If need be, clubs may sign a goalkeeper on an emergency loan, if all others are unavailable. Clubs are able to purchase players again in May when the window re-opens.
