The Australian Women's Twenty20 Cup (WT20) was the premier domestic women's Twenty20 cricket competition in Australia. Beginning in 2007 as a series of exhibition matches, the first official tournament took place during the summer of 2009–10. All seven state and territory representative teams from its 50-over counterpart, the pre-existing Women's National Cricket League, participated in the WT20's formal six-year span. The competition was replaced by the Women's Big Bash League in 2015.
The Victorian Spirit were the most successful team, having managed to claim three titles in a row. The New South Wales Breakers finished on top of the ladder at the conclusion of every regular season, but they lost three consecutive championship deciders against Victoria before eventually winning two titles of their own. The Queensland Fire also won one title.
