Sérgio Luis Gardino da Silva (born 9 December 1979), commonly known as Serjão, is a Brazilian former footballer who played as a striker.
Born in Alvorada, Rio Grande do Sul, Serjão only played lower league or amateur football in his country.
In 2004, after a very brief spell in Uruguay, he moved to Portugal after signing with Portimonense SC in the second division, where his performances attracted the attention of Académica de Coimbra in the Primeira Liga, who acquired the player in the 2006 January transfer window.
Serjão scored his first and only goal in the top level of Portuguese football in just his second appearance, contributing to a 3–0 home win against F.C.
He scored a career-best 24 goals to help his team to the eighth position among 14 clubs, but netted only 19 times in the next four years combined, also playing in the country's top flight and representing AEL Limassol, Alki Larnaca FC, Ermis Aradippou, Ethnikos Achna FC and AEP Paphos FC.
