1. Fußball-Club Köln 01/07 e. V., commonly known as simply 1. FC Köln or FC Cologne in English, is a German association football club based in Cologne. It was formed in 1948 as a merger of the clubs Kölner Ballspiel-Club 1901 and SpVgg Sülz 07. Köln play in the Bundesliga, the highest league of German football.
The club's nickname Die Geißböcke refers to the club's mascot, a male goat named Hennes after the veteran FC player and manager Hennes Weisweiler. The first Hennes was donated by a circus entrepreneur as a Cologne carnival joke. The current mascot is Hennes VIII, and has been since 24 July 2006. Another nickname for the club, more common locally due to its ambiguity, is FC, a common German abbreviation for football clubs. Characteristic for the dialect spoken around Cologne, this is pronounced "EF-tsay", in contrast to the Standard German pronunciation of the abbreviation where the second syllable is emphasized.
Like many of Germany's other professional football clubs, 1. FC Köln is part of a larger sports club with teams in other sports like handball, table tennis and gymnastics. 1. FC Köln has over 100,000 members, making it the fourth largest club in Germany.
