The 2020 NAIA Division I women's basketball tournament was the tournament scheduled to be held by the NAIA to determine the national champion of women's college basketball among its Division I members in the United States and Canada for the 2018–19 basketball season.

The NAIA cancelled the tournament due to the COVID-19 pandemic.

Due to the planned consolidation of the two NAIA divisions into a single division ahead of the 2021 tournament, this was also scheduled to be the final edition of a separate Division I NAIA women's tournament.

The tournament was due to be played at the Rimrock Auto Arena at MetraPark in Billings, Montana.
