Marko Rehmer (born 29 April 1972) is a German former professional footballer who played mainly as a right-back.

FC Union Berlin; he arrived in the first division at almost 25, joining former East Germany's Hansa Rostock during the 1997 winter transfer window.

For the following six years, Rehmer played with another club from his city, Hertha BSC; being an important defensive unit as the side always made the UEFA Cup in the first four seasons, he was also grossly undermined by several injuries.

Following more injuries,[4] he was forced to retire at the end of 2006–07, after helping with 12 matches in the team's final escape from relegation.

His best years were 2000–01, as he played in 20 internationals, including twice at UEFA Euro 2000, where the national side – the holders – were ousted in the group stages; he was also summoned to the 2002 FIFA World Cup, getting a runners-up medal with his 45 minutes against Paraguay, in the round of 16 (1–0).
