The 2021 FAI Women's Cup (known as The EVOKE.ie FAI Women's Cup for sponsorship reasons) is the 46th edition of the Republic of Ireland's primary national knockout cup competition for women's association football teams. The nine Women's National League (WNL) teams entered the competition, but unlike in previous years no non-league teams took part. The competition began on 13 August 2021 with a single-fixture first round and concluded on 21 November 2021. The final was staged at the Tallaght Stadium in Dublin, which had also hosted the previous year's final.
