Arena do Grêmio, Football stadium in Porto Alegre, Brazil.

Arena do Grêmio is a football stadium in Porto Alegre, Brazil, with a broad white roof that has a rectangular opening at its centre. Through the opening, rows of blue seats descend to a pitch marked in blue and white. The facade combines a band of blue glass panels with grey concrete, and white capital letters reading "ARENA DO GRÊMIO" are mounted on the glass.

Construction began in September 2010 on land to the north of the city center. The facility opened in December 2012, taking over from the previous home ground that had served the club for decades.

The venue takes its name from Grêmio Foot-Ball Porto Alegrense and on match days displays blue, white and black club colors throughout its stands. Supporters gather wearing team jerseys and scarves, filling the tiers with chants and rhythmic singing that echo across the bowl during games.

Parking is available inside the complex with covered spaces for visitors arriving by car. Access roads connect the site to major routes across Porto Alegre, making arrival straightforward from different parts of the city.

Arena do Grêmio was chosen as one of the venues for the 2019 Copa América, hosting five matches, including the semi-final in which Peru beat Chile 3–0. The stadium was not selected as a host venue for the 2014 FIFA World Cup held in Brazil.
