The 2021 Inter-Insular Women's T20 Series was scheduled to be played in July 2021 and would have seen Guernsey women's cricket team tour Jersey for three Women's Twenty20 International (WT20I) matches.[1] The series was to be played at Farmers' Field in Saint Martin.[2] The traditional annual 50-over Inter-insular match between the men's teams of Jersey and Guernsey was scheduled to follow in August 2021, if conditions had allowed.[3] Guernsey won the single WT20I when the sides last met during the 2019 T20 Inter-Insular Cup.[4]
Junior inter-insular matches were also scheduled for early July.[5] However, these games were cancelled due to ongoing travel restrictions between the two islands as a result of the COVID-19 pandemic, with the women's series and men's match also put in doubt.[6] The women's series and the men's match were later postponed due to continued travel restrictions between the islands.[7] The boards announced that they hoped to play home and away series in 2022 if space can be found in their schedules.[8]
