Australia women's cricket team in New Zealand in 2020–21

The Australia women's cricket team played against New Zealand women's cricket team in March and April 2021. The tour took place during the time that was originally scheduled to be used to host the 2021 Women's Cricket World Cup. However, the tournament was postponed by one year due to the COVID-19 pandemic. The fixtures for the tour were confirmed in January 2021, with three Women's Twenty20 International (WT20I) and three Women's One Day International (WODI) being played. The WT20I matches were played as double-headers alongside the men's fixtures between New Zealand and Bangladesh.

Australia won the first WT20I by six wickets, with New Zealand winning the second match by four wickets to level the series. Only 2.5 overs of play was possible in the third WT20I, with the series being drawn 1–1.

Australia won the first WODI by six wickets, setting a new record of twenty-two consecutive wins in ODI cricket. This broke the previous record of twenty-one wins set by Ricky Ponting's team of 2002–03. Australia won the second WODI by 71 runs, winning the series and retaining the Rose Bowl. Australia won the third WODI by 21 runs to win the series 3–0.
