André Muniz de Aguiar (born February 17, 1990) is a Brazilian professional mixed martial artist who competes in the Middleweight division of the Ultimate Fighting Championship.

Born in Montes Claros, Minas Gerais, Muniz was a very active teenager, which made his mother sign him up for Jiu-Jitsu classes to see if he could get calmer and more disciplined.

[5] Muniz attended Faculdades Unidas do Norte de Minas, from where he graduated with bachelor's degree in physical education with honors.

[6] Muniz started his career travelling back and forth between his hometown and Rio de Janeiro, training with the likes of Thiago Santos and Luis Henrique at Tata Fight Team, and earning extra money on the side as a personal trainer to make ends meet in between fights.

[9] Almost a year later, Muniz returned to DWCS to face undefeated Taylor Johnson at Dana White's Contender Series 23 on August 6, 2019.

[11] Muniz made his sophomore appearance against Bartosz Fabiński at UFC Fight Night: Overeem vs. Sakai on September 5, 2020.

[39] However, the bout was cancelled once again due to Muniz's and his team's visa issues and was rescheduled for April 26, 2025 at UFC Fight Night 257.

In a December 2021 interview with Sherdog, Muniz said that he used the bonus money that he won for his performance against Bartosz Fabinski at UFC Fight Night: Overeem vs. Sakai to purchase a plot of land where he plans to build a home for his family.
