List of Spanish football transfers summer 2017

This is a list of Spanish football transfers for the summer sale in the 2017–18 season of La Liga and Segunda División. Only moves from La Liga and Segunda División are listed.

The summer transfer window began on 1 July 2017, although a few transfers took place prior to that date. The window closed at midnight on 1 September 2017. Players without a club can join one at any time, either during or in between transfer windows. Clubs below La Liga level can also sign players on loan at any time. If needed, clubs can sign a goalkeeper on an emergency loan, if all others are unavailable. Unless noted, all of the clubs without a flag are from Spain.
