Alemannia Aachen (German pronunciation: [ʔaleˈmani̯a ˈʔaːxən]) is a German football club from the western city of Aachen, North Rhine-Westphalia. A long term fixture of the country's second division, Alemannia enjoyed a three-year turn in the top flight in the late 1960s and, after a successful 2005–06 campaign, returned to first division play for a single season. The club has since slipped to third division play and in late 2012 entered into bankruptcy. They finished their 2012–13 3. Liga schedule before resuming play in the tier IV Regionalliga West in 2013–14.
Alemannia carries the strange nickname "the Potato Beetles" (Kartoffelkäfer) because of their striped yellow-black jerseys, which make them look like the particular insects.
