Cantigas do Maio (English: "Songs of May") is the fifth studio album by Portuguese singer-songwriter José Afonso.

[1][2][3] It contains Afonso's most iconic song, "Grândola, Vila Morena", which was used as a radio-broadcast signal by the Portuguese Armed Forces Movement during their military coup operation on the morning of 25 April 1974, which led to the Carnation Revolution and the transition to democracy in Portugal.

Cantigas do Maio was recorded between 11 October and 4 November 1971 at the Strawberry Studio in Château d'Hérouville, in Hérouville, France.

It was re-released on CD and vinyl, and made available for the first time on streaming services, in April 2022.

[4] In 1978, the Portuguese weekly-magazine SETE awarded Cantigas do Maio the "Award for Greatest Album Ever of Portuguese Folk Music" (Prémio Melhor Disco de Sempre da Música Popular Portuguesa).
