Estádio Décio Vitta, Football stadium in Americana, Brazil.

Estádio Décio Vitta, nicknamed Riobrancão, is a football ground in Americana opened on 1 May 1977, with a current capacity of 16,300. It is owned by Rio Branco Esporte Clube and named after Décio Vitta, a club counselor and director who coordinated its construction.

In 1954 Rio Branco gave up its field to the city of Americana, which built the Instituto de Educação Presidente Kennedy there; in exchange the club received a 50,000 m² plot in Vila São Domingos, donated by Antonio, José Dante and João Zanaga. Construction of the stadium began in 1971 and it opened on 1 May 1977 as Riobrancão. In 1981 president Délcio Dollo proposed renaming it after Décio Vitta, a club counselor and director who coordinated the works; the change took effect in 1986.

Rio Branco took over the ground in 1979 after absorbing Americana EC, which had played the 1977 inaugural match there. The club is nicknamed Tigre, and the stadium is called Riobrancão. Décio Vitta, the man the ground is named after, was a Rio Branco counselor and director who coordinated its construction.

The stadium sits in the Vila São Domingos area of Americana, on a 50,000-square-metre plot donated by Antonio, José Dante and João Zanaga. Rio Branco took over its own administration again on 1 May 2017, ending the 30-year comodato with the city hall that began in 2009.

The stadium's record crowd of 19,173 came on 9 March 1993, when Rio Branco beat São Paulo 1-0 in the Campeonato Paulista, with Edmar scoring in the 29th minute of the second half. An unofficial estimate of 25,000 spectators was reported on 12 October 1982, when gates were opened free of charge for Rio Branco's 6-0 win over Primavera de Indaiatuba.
