FA WSL Spring Series

The FA WSL Spring Series was an interim edition of the FA WSL between the sixth and seventh full seasons. The Spring Series ran from February to May 2017 to bridge the gap from the 2016 FA WSL season which ran from March to September as a summer tournament, and the 2017–18 season which started in September 2017.

While the 2017–18 season planned to feature 21 clubs, the Spring Series contained 20. Notts County Ladies F.C. folded two days before they were due to play their first Spring Series game, leaving 19 teams in total. Teams played each other once, with no promotion or relegation before the full 2017–18 season. WSL 2 began in February, while WSL 1 started in April.
