The National Renewal Alliance (Portuguese: Aliança Renovadora Nacional, ARENA) was a far-right political party that existed in Brazil between 1966 and 1979. It was the official party of the military dictatorship that ruled Brazil from 1964 to 1985.

ARENA was part of a two-party system enforced by the dictatorship instituted in 1966, where only it and the Brazilian Democratic Movement (MDB) — the "consented opposition" — were allowed. In 1979, a multi-party system was reintroduced to Brazil, both MDB and ARENA were officially dissolved, and the Democratic Social Party (PDS) was founded as a continuation of ARENA. Soon thereafter, PDS had a split which saw the creation of the Liberal Front Party (PFL), current Brazil Union (UNIÃO), while PDS merged with the PDC in 1993 became the Reform Progressive Party (PPR), which became the current Progressives (PP) in 1995.
