Estádio Municipal José Maria de Campos Maia, Municipal football stadium in Mirassol, Brazil.

Estádio Municipal José Maria de Campos Maia, known as Maião, is a football ground in Mirassol with a natural grass pitch measuring 102 by 70 metres. Its capacity is given as 19,000 in Portuguese sources and 14,534 in English ones. The stands are divided into general public, VIP and privileged court areas.

The ground was donated by José Maria de Campos Maia, a businessman and mayor of Mirassol (1951; 1956–1959), as a gift to the town. The stadium was inaugurated on 3 March 1983 with a match between Mirassol and Jalesense, and was reinaugurated on the same date. In 2017 the club spent R$ 230,000 on new turf and a drainage and irrigation system.

The stadium is named after José Maria de Campos Maia, a businessman and mayor of Mirassol in 1951 and from 1956 to 1959, who donated the land for its construction as a gift to the people of Mirassol. The name is used alongside the popular nickname Maião.

The stadium sits on Avenida Lauro Luchesi in Mirassol, with the pitch measuring 102 by 70 metres. Sources give capacities of 14,534 and 19,000, so expect standing areas rather than numbered seats. The record crowd, 11,967, came on 10 February 2018 for Mirassol against Palmeiras.

On 8 April 2026 the Maião hosted Mirassol's first international night: a 1-0 win over Lanús in the club's opening Copa Libertadores match. The ground had already seen Mirassol beat Palmeiras 6-2 in 2013, the heaviest Paulistão defeat suffered by Palmeiras that century.
