Mariano Rodrigues Amaro (7 August 1914 – 22 May 1987) was a Portuguese football midfielder and manager.
Amaro was born in Lisbon. He spent his entire career with local club C.F. Os Belenenses, always in the Primeira Liga.[1]
In the 1945–46 season, captain Amaro contributed 22 appearances as the team won the national championship for the first and only time in their history.[2]
Amaro earned the first of his 19 caps for Portugal on 28 November 2017, in a 2–1 friendly win against Spain in Vigo. Before that match he, alongside teammates João Azevedo, Artur Quaresma and José Simões, refused to perform the fascist salute, being subsequently questioned by PIDE.[3]
