Marcos Pereira Martins (born 1 April 1943), simply known as Marcos, is a Brazilian former professional footballer who played as a right winger.
Marcos started his career at Jabaquara in 1961, without playing much that season. In 1962, he was the team's highlight, drawing the attention of SC Corinthians due to his dribbling ability. His only title for the club was the Rio-São Paulo Tournament shared in 1966, and for the club he made 189 appearances with 27 goals scored. He was loaned to Bangu as part of the negotiation for Paulo Borges, but did not establish himself. He also played for Portuguesa Santista and in Argentine football.
For the Brazil national team, Marcos participated in six official matches, in addition to other performances in unofficial games like against Arsenal F.C. in 1965.
After retiring from football, he worked as a watchmaker and jeweler alongside his uncle.
