Background
The event was originally expected to be held at Arena da Baixada in Curitiba. However, the event was relocated to Jeunesse Arena in Rio de Janeiro, after the UFC failed to come to terms with Athletico Paranaense.

A UFC Women's Strawweight Championship bout between current champion Rose Namajunas and Jéssica Andrade served as the event headliner.

A bout between former bantamweight title challenger Bethe Correia and Irene Aldana took place at the event. The match up was originally scheduled to take place in August 2018 at UFC 227, but Correia pulled out of that event, citing injury. At the weigh-ins, Correia weighed in at 141 pounds, 5 pounds over the women's bantamweight non-title fight limit of 136. As a result, Correia was fined 30 percent of her purse, and the bout proceeded at a catchweight.
