The 2020 Scottish Women's Premier League, known as the Scottish Building Society Scottish Women's Premier League for sponsorship reasons, was due to be the 19th season of the Scottish Women's Premier League, the highest division of women's association football in Scotland since its inception in 2002. Glasgow City were the defending champions. Heart of Midlothian joined the SWPL 1 as the promoted club from the 2019 SWPL 2, replacing Stirling University.
The season started on 21 February 2020 and was scheduled to end in November 2020, but was interrupted by the coronavirus pandemic. In July 2020, the 2020 season was declared null and void. A new season started on 18 October 2020 and concluded on 4 July 2021, with the league reverting to a winter season format.
