Rádio Renascença is a private, commercial radio station based in Lisbon, Portugal, owned by various organizations within the Portuguese Catholic Church. Founded in 1934 by Monsignor Lopes da Cruz, it began regular broadcasting in 1937 as a full-service radio station aimed at a broader audience, not just Catholics.

The station played a significant role in Portuguese history, particularly during the Carnation Revolution of 1974. Just after midnight on April 25, 1974, Rádio Renascença broadcast the banned song "Grandola, Vila Morena," which served as a signal to the revolutionary Armed Forces Movement to commence operations against Portugal's authoritarian government.

Today, Rádio Renascença is part of the R/Com group, one of Portugal's two main private radio groups. It offers a diverse programming mix including news, entertainment, sports, and religious content. The station broadcasts nationwide on FM and is also available online.

Rádio Renascença's programming includes popular shows such as "Manhã da Renascença" with Carla Rocha, news programs like "Bola Branca" for sports coverage, and various talk shows and music programs throughout the day. The station maintains its Catholic roots while appealing to a wide audience with its general interest content.
