Arena MRV, Football stadium in California district, Belo Horizonte, Brazil.

Arena MRV is a football stadium in the California district of Belo Horizonte with 44,892 seats in two tiers, a lower ring close to the pitch and an upper ring above, separated by a continuous red band. A white roof on a steel truss surrounds the stands and is open in the middle. A rectangular screen hangs high on one side, and advertising boards with "BMG" line the field.

Building work started in April 2020 after Atlético Mineiro sold its share in Diamond Mall to fund the project. The venue opened in April 2023, giving the club a dedicated home for the first time since 1950.

The arena's name comes from MRV Engenharia, which paid R$60 million for ten years of naming rights; the club's own nickname, Galo, appears in the Instituto Galo social body created as a condition of the environmental licence. The first match, on 16 July 2023, was a festival game between teams of former Atlético players, with Dadá Maravilha taking the kick-off. Atlético's competitive debut came on 27 August 2023, a 2–0 win over Santos with Paulinho scoring the first goal.

The arena sits on Avenida Presidente Juscelino Kubitschek in the Noroeste region, near the Anel Rodoviário and Eldorado metro station. The environmental licence required bike paths linking the ground to that station. The esplanade holds a health centre and a day care centre built as counterparts.

Architect Bernardo Farkasvölgyi designed an acoustic system that keeps sound contained during concerts and sporting events. This setup allows for controlled sound management when the venue is closed.
