The 2019–20 Louisiana Ragin' Cajuns women's basketball team represented the University of Louisiana at Lafayette during the 2019–20 NCAA Division I women's basketball season.

The Ragin' Cajuns were led by eighth-year head coach Garry Brodhead and played all home games at the Cajundome along with the Louisiana Ragin' Cajuns men's basketball team with the exception of their March 5 meeting with UT Arlington at Earl K. Long Gymnasium, the first basketball game to be held there since 2016.

On March 12, the Sun Belt Conference cancelled the remainder of their women's and men's basketball tournaments due to rising threats of the COVID-19 pandemic.

The Cajuns were scheduled to play Troy in the upcoming weekend.

They made it to the 2018-19 Sun Belt Conference women's basketball tournament before losing to the South Alabama Jaguars 61–73 in the first-round game.
