The 2021–22 Scottish Women's Premier League was the 21st season of the SWPL, the highest division of women's football in Scotland since 2002. The league is split into two divisions – SWPL 1 with 10 teams[1] and SWPL 2 with seven teams, following the sudden resignation of Forfar Farmington in August 2021[2] – Partick Thistle were elevated to SWPL 1 to maintain an even number of teams, leaving SWPL 2 one short.
The league season started on 5 September 2021 and ended on 15 May 2022.[3] The competition was known as the Scottish Building Society Scottish Women's Premier League for sponsorship reasons,[4] then as the Park's Motor Group Scottish Women's Premier League from November 2021.[5]Glasgow City were the defending champions of 14 consecutive seasons.
In February 2022, Glasgow City lost 3–1 away to Rangers in a pivotal fixture;[6] a 0–0 draw in the reverse fixture on 8 May gave Rangers the SWPL 1 championship, their first Scottish women's title.[7] The Gers finished seven points ahead of Glasgow City and only dropped four points, via two draws against the deposed champions, defeating all other opponents three times for an unbeaten season. They also qualified for the UEFA Women's Champions League for the first time.[8]
Two clubs were promoted from SWPL 2 and none relegated from SWPL 1 due to league expansion.[13] The league's first promotion/relegation play-off had been planned[14] until the expansion was confirmed in April 2022[13] following the SWPL clubs' majority vote to leave SWF for the SPFL in February.[15]
