Women's Twenty20 international (WT20I) is the shortest form of women's international cricket. A women's Twenty20 international is a 20 overs-per-side cricket match between two of the International Cricket Council (ICC) members. The very first Twenty20 International match was played on 5 August 2004 between England and New Zealand at Hove, six months before the first Twenty20 International match was played between two men's teams. The Women's T20 World Cup, the highest-level event in the format, was first held in 2009.
In April 2018, the ICC granted full women's Twenty20 international (WT20I) status to all its members. Therefore, all Twenty20 matches played between two international sides after 1 July 2018 will be a full WT20I. A month after the conclusion of the 2018 Women's Twenty20 Asia Cup, which took place in June 2018, the ICC retrospectively gave all the fixtures in the tournament full WT20I status. On 22 November 2021, in the 2021 ICC Women's T20 World Cup Asia Qualifier tournament, the match between Hong Kong and Nepal was the 1,000th WT20I to be played.
