1. FC Düren

FC Düren-Niederau was founded in the year 1908 as FC 08 Niederau-Krauthausen and later adopted the name FC Düren-Niederau. The team's greatest success was being promoted into the Verbandsliga Mittelrhein in 1981, in which they would later go on to reach fourth place in the 1984/85 season — the best performance in the club's history. In 1991 the club were relegated from the league. In 2008 they were re-promoted into the league, but were shortly relegated at the end of the next season. In 2012 they then were relegated further from the Verbandsliga to the Bezirksliga, but promptly re-entered the Verbandsliga the following season. Their junior teams also showed great success, with the C-Juniors winning the Mittelrheinpokal in 2005 and 2012, and the D-Juniors in 2000 and 2004. Johanna Elsig became the 2009 UEFA Women's Under-17 Championship champion.

The partnering club to 1. FC Düren, SG GFC Düren 99, is a product of multiple fusions between other clubs and a team associated with two German national football team players: Karl-Heinz Schnellinger and Georg Stollenwerk. Their roots stem back to 1899, where the team was founded as Germania Düren. On August 8th 1935 this team would then fuse with Düren SC 03 to form SG Düren 99. SG Düren 99 would go on to play in the top division Gauliga Mittelrhein league during the 1930s, and then later in the second division 2. Oberliga West following the end of World War II. During the 1980s and 90s the club were often without success found themselves in a downward spiral and would end up in Kreisliga B. On June 29th 2001 the team would fuse with Schwarz-Weiß Düren to form SG Schwarz-Weiß Düren 99. Six years later, however, Schwarz-Weiß Düren was re-founded as a separate team. On April 1st 2011 SG Düren 99 merged with GFC Düren 09, who had played in the fourth division Oberliga Nordrhein from 2002-2007, to form the current team: SG GFC Düren 99.
