The 2020–21 Women's Big Bash League season or WBBL|06 was the sixth season of the Women's Big Bash League (WBBL), the semi-professional women's Twenty20 domestic cricket competition in Australia. The tournament took place from 25 October to 28 November 2020. It was played entirely in Sydney due to ongoing state border restrictions brought about by the COVID-19 pandemic. Sophie Devine was named in her first season with the Perth Scorchers, earning the same award she won in WBBL|05 while playing for the Adelaide Strikers.
