Associate international cricket in 2021

The 2021 Associate international cricket season was from May to September 2021. All official twenty over matches between Associate members of the ICC were eligible to have full Twenty20 International (T20I) or Women's Twenty20 International (WT20I) status, as the International Cricket Council (ICC) granted T20I status to matches between all of its members from 1 July 2018 (women's teams) and 1 January 2019 (men's teams). The season included all T20I/WT20I cricket series mostly involving ICC Associate members, that were played in addition to series covered in International cricket in 2021. In July 2021, Mongolia and Tajikistan were awarded Associate Membership of the ICC, and Switzerland were also readmitted as associate members.
