2021 Women's British Open Squash Championship

The Women's 2021 Allam British Open was the women's edition of the 2021 British Open Squash Championships, which is a 2020–21 PSA World Tour event. The event took place at the Sports Complex at the University of Hull in Hull in England between August 16 and 22, 2021. The event was sponsored by Dr Assem Allam.

The event was arranged for June instead of May because of the COVID-19 pandemic in the United Kingdom and then rearranged for August. The 2020 event had also been cancelled due to the pandemic.

Nour El Sherbini defeated Nouran Gohar in an all Egyptian final, which saw Nour El Sherbini winning the title for the third time.
