Ayrton Moreira (31 December 1917 – 22 November 1975), sometimes called Aírton Moreira, was a Brazilian football manager and former player who played as a central defender.
Moreira was in charge of América Mineiro in 1956, before taking over Cruzeiro in the following year. He returned to Atlético for a brief period in 1959, and subsequently worked at Cruzeiro in several roles.
In 1964, after the club dismissed Marão, Moreira was named manager of Cruzeiro's first team. He led the club to the 1966 Taça Brasil win over Pelé's Santos, but had to step down in November 1967 due to illness.
In 1968, Moreira was named Atlético Mineiro manager for a third period. He was subsequently in charge of Bela Vista-MG, Valeriodoce and Vila Nova[3] before returning to Cruzeiro in 1975, but now as an assistant.
