List of centuries in women's Twenty20 International cricket
In the sport of cricket, a century is a score of one hundred or more runs by a batsman in a single innings. In a women's Twenty20 match, each team plays a single innings, which is restricted to a maximum of 20 overs. A women's Twenty20 International is an international cricket match between two teams, each having WT20I status, as determined by the International Cricket Council, the sport's world governing body. The Twenty20 format was originally introduced by the England and Wales Cricket Board for the men's county cricket competition, with the first matches contested on 13 June 2003 between the English counties in the Twenty20 Cup. The first women's Twenty20 International match took place on 5 August 2004 when New Zealand defeated England by nine runs at the County Cricket Ground in Hove. This match was held six months before the first men's Twenty20 International, which was contested between Australia and New Zealand in February 2005.
The first century in a WT20I match was scored by Deandra Dottin of the West Indies. Dottin posted 112 not out against South Africa in the opening match of the 2010 ICC Women's World Twenty20 at Warner Park in Basseterre. Dottin's innings is the fastest WT20I century, and is the WT20I century with the highest strike rate. Batting at number six, Dottin's innings is one of two occasions where a WT20I century has been scored by a player batting at number five or lower. The other was when India's Harmanpreet Kaur, who came in at number five, posted 103 against New Zealand during the 2018 ICC Women's World Twenty20. Dottin, Danni Wyatt of England and Australia's Meg Lanning and Beth Mooney are the only players to have achieved the feat two times. Both of Wyatt's WT20I centuries were scored in the second innings of the match. The only other instance was when Sri Lanka's Chamari Atapattu made 113 against Australia during the WT20I series in September 2019. Sri Lanka lost the match, and it was one of two occurrences where a team was defeated in spite of a player scoring a century. This match was also one of four occasions where two WT20I centuries were scored in the same match.
The most recent century, as of 2020, was scored by South Africa's Lizelle Lee against Thailand at Manuka Oval in Canberra during the 2020 ICC Women's T20 World Cup, which is currently being contested in Australia. The highest individual score of 148 not out in WT20Is was achieved by Australia's Alyssa Healy against Sri Lanka in October 2019. It is the only WT20I century that has been scored by a designated wicket-keeper. The oldest player to score a WT20I century is New Zealand's Suzie Bates, who was aged 30 years and 277 days when she reached 124 not out against South Africa in June 2018. At the age of 16 years and 233 days, Uganda's Prosscovia Alako became the youngest player to score a WT20I century when she made 116 against Mali at the 2019 Kwibuka Women's T20 Tournament in Rwanda.
, a total of 26 centuries have been scored by 22 different players from 861 WT20I matches. Centuries have been scored by players from 13 of the 61 teams that hold women's Twenty20 International status and have played a WT20I match. Australia leads the list with five, followed by England with four and the West Indies with three centuries. Centuries have been scored at sixteen different grounds, with Rwanda Cricket Stadium in Kigali and Manuka Oval in Canberra both leading the list with four, followed by North Sydney Oval with three.
