This is a list of Belgian football transfers for the 2017-18 winter transfer window.
Only transfers involving a team from the professional divisions are listed, including the 16 teams in the 2017–18 Belgian First Division A and the 8 teams playing in the 2017–18 Belgian First Division B.
The winter transfer window opens on 1 January 2018, although a few transfers may take place prior to that date.
The window closes at midnight on 1 February 2018 although outgoing transfers might still happen to leagues in which the window is still open.
Players without a club may join teams, either during or in between transfer windows.
Some players were on a loan which ended in 2017.
As of 1 January 2018, they returned to their original club and are listed here.
