Antonio Britto Filho (born 1 July 1952) is a Brazilian journalist and politician, who held the positions of Congressman, Social Security Minister, and Governor of the state of Rio Grande do Sul.

The son of a journalist, he began working in a small local newspaper for his father, before completing his studies in journalism at the Federal University of Rio Grande do Sul.

In 1972, he moved to radio Guaíba (belonging to the Junior Caldas), at the invitation of Peter Pereira Carneiro, where he became coordinator of the area and was head of sports journalism.

In 1988 he was appointed as the PMDB candidate for mayor of Porto Alegre, but despite the initial favoritism, faded and finished fourth in the election, which was won by Olivio Dutra (Workers Party, PT).

The management ahead of the government of Rio Grande do Sul was marked by administrative reforms and a heated controversy with the opposition (led by the PT), which held the hegemony of the unions of servers, especially the CPERS, which combines the teaching state.

But in some cases favouring the PPB (who appointed his running mate, José Otávio Germano) led to splits within his own party, which in some municipalities announced support for the PT.

In 2001, still tipped as favourite for the succession of Olivio Dutra (who would not be running for reelection), Antonio Britto clashed with Sen. Peter Simon, the main regional leader of the PMDB, and ended up leaving the party.

Since then, Britto announced his abandonment of politics, becoming director of the company Azaléia, and its president, after the death of its founder, Nestor de Paula, who approached the government for state.

In 2005, he became involved in a national controversy when closing a factory unit in Rio Grande do Sul, laying off 800 employees, while opening a plant in China.
