Theo Zwanziger (born 6 June 1945) is a German lawyer and sports official.

[2] In 1992, Zwanziger entered the DFB as a member of the executive board ("Mitglied des Vorstandes").

[3] He was a vital part of the groundbreaking 2001 decision to grant autonomy to the German Bundesliga professional teams, letting them organise themselves in the DFL (Deutsche Fußball-Liga).

[1] When the renowned sport journalist Jens Weinreich called him an "unglaublicher Demagoge" (unbelievable demagogue), Zwanziger unsuccessfully asked the Landgericht Berlin (country court of Berlin) to issue a temporary injunction against this statement.

Zwanziger later publicly announced to go to the court of Koblenz, his former place of work for another attempt, resulting in further criticism from the press and journalists' associations.
