Sri Lanka women's cricket team in Australia in 2019–20

The Sri Lanka women's cricket team played the Australia women's cricket team in September and October 2019. The tour consisted of three Women's One Day Internationals (WODIs), which formed part of the 2017–20 ICC Women's Championship, and three Women's Twenty20 International (WT20I) matches. It was the first bilateral series played by Sri Lanka Women in Australia.

In the third and final WT20I match of the series, Australia's Alyssa Healy set a new record for the highest individual score in a Women's T20I match, with 148 not out. Australia won the WT20I series 3–0. Australia won the first two WODI matches to take an unassailable lead in the series. Their win in the second match was their 17th consecutive win in WODIs, which equalled the record for most consecutive wins in the format. The victory also confirmed Australia as the winners of the 2017–20 ICC Women's Championship. Australia went on to win the third WODI by nine wickets, winning the series 3–0, and setting a new record for the most consecutive wins in WODIs, with 18.
