Estrela Clube Primeiro de Maio, usually known simply as Primeiro de Maio or 1º de Maio, is a football (soccer) club from Benguela, Angola.

The club was the result of a merger from two clubs: Estrela Vermelha de Benguela and Grupo Desportivo 1º de Maio[1] being then named África Têxtil 1º de Maio de Benguela due to its then major sponsor, a Benguela-based textile factory called África Têxtil.

Shortly afterwards, the name was changed to its present denomination.

Moreover, Primeiro de Maio became in 1994, the first Angolan club to reach the final of a CAF competition and to win the Angola Cup and the Angola Super Cup.
