Jannis Zamanduridis (born March 18, 1966 in Chemnitz, East Germany) is a retired amateur German Greco-Roman wrestler, who competed in the men's welterweight category.
Considered as one of Germany's most promising wrestlers in his decade, Zamanduridis has claimed two medals (one silver and one bronze) in the 68-kg division at the World Championships (1990 and 1995), but took an early hiatus shortly to focus on his coaching staff for the German wrestling team.
In 2003, Zamanduridis suddenly came out of his impending retirement to compete for Germany at the 2004 Summer Olympics.
Throughout his sporting career, Zamanduridis trained full time as a member of the wrestling club for KSV Köllerbach, under his personal coach Frank Hartmann.
