FC Hanau 93 is a German association football club based in Hanau, Hesse.
Founded in 1893, the club is Hesse's oldest. In its first year, the club was winless in a half dozen matches, but the next season emerged as south German champion and earned an appearance in a national championship match. Hanau was one of the founding clubs of the German Football Association formed in 1900.
In those early days of German football Hanau laid a 23–1 drubbing on a hopelessly green Kickers Offenbach side. The club managed a series of unsuccessful appearances in the local league final between 1902 and 1905 and were "robbed" of a title through bureaucratic machinations in 1907, before finally taking the local title in 1909. It became a founding member of the Nordkreis-Liga in 1909, where it played until the outbreak of the war. After the First World War, the club played in the Kreisliga Nordmain without any real success. In 1926, Hanau found itself in a legal squabble with FSV Frankfurt and the league that led to its exclusion from play for a short time. Through the late 1920s and into the 1930s the team played in the Bezirksliga Main-Hessen of the Süddeutschland Verband.
German football was reorganized into sixteen top-flight divisions, or Gauligen, under the Third Reich in 1933. Playing in the Gauliga Hessen Hanau captured three more regional titles in the late 1930s (1935, 1936, 1938) and advanced to the quarter finals of the inaugural Tschammerpokal, predecessor of today's DFB-Pokal, in 1935. The Gauliga Hessen was broken up into two divisions in 1941 with the club going to the Gauliga Hessen-Nassau where they played consistently good football until the collapse of football leagues in Germany at the end of World War II. In spite of their play they were not granted entry to the local upper tier leagues once re-established after the war, being bypassed for clubs from larger towns, and losing their ground to the American military.
