Estádio Décio Vitta, nicknamed Riobrancão, is a multi-use stadium located in Americana, São Paulo, Brazil.

In 1954, Rio Branco ceded its football field to the São Paulo state government, which built a state school there, and in exchange, the government ceded a new groundplot to the club.

In 1971, the stadium construction started, after Rio Branco and the Americana city hall came to an agreement.

In 1981, Rio Branco's president at the time, Délcio Dollo, proposed the stadium to be renamed Décio Vitta, however, this happened only in 1986.

The stadium's attendance record currently stands at 19,173, set on March 9, 1993, when Rio Branco beat São Paulo 1–0.
