Günter Theodor Netzer (born 14 September 1944) is a German former professional football player, executive and pundit. He achieved great success in Germany with Borussia Mönchengladbach in the early 1970s and, after moving to Spain in 1973, with Real Madrid. A technically gifted playmaker, Netzer played as an attacking midfielder and is considered one of the greatest passers in the game's history. He was voted German Footballer of the Year twice, in 1972 and 1973.

Netzer was the general manager for Hamburger SV during much of the team's golden period from the late 1970s through the early 1980s, when the club won three league titles and the 1983 European Cup.
