TuRU Dusseldorf is a German sports club (football and handball) from the city of Dusseldorf, North Rhine-Westphalia.
Turn- und Rasensport Union Dusseldorf claims a number of early Dusseldorf clubs in its heritage. Dusseldorf Fusball Klub Union was created on 10 May 1905 as Dusselsdorfer Fusball Klub Union through the merger of Vorwarts Dusseldorf and Borussia Dusseldorf with onetime members of Fusball Club Britannia Dusseldorf. The club was renamed Dusseldorfer Sport Club Union in 1911 and in 1913 advanced to the final of the Westdeutcher Fusball Verband where they lost to Duisburger Spielverein, which then went on to the national final against VfB Leipzig. SC joined Verein fur Rasensport Dusseldorf and Friedrichstadter Turnverein 1880 to form TuRU in 1919. Until July 1916 VfR had played as Sport Club Athen Dusseldorf.
TuRU in its turn advanced to the final of the Westdeutcher Fusball Verband in 1923 where they dropped a 3:4 decision to Arminia Bielefeld. Two years later they avenged themselves on both Duisburger SV and Bielefeld, defeating these sides on their way to a national quarterfinal match up versus Hertha BSC Berlin where they were eliminated.
From 1935 to 1942 Dusseldorf played in the Gauliga Niederrhein, one of sixteen top flight divisions formed in the 1933 reorganization of German football under the Third Reich.
