Pfaffenhofen an der Ilm (German pronunciation: [pfafn̩ˈhoːfn̩ ʔan deːɐ ʔɪlm], lit.

'Pfaffenhofen on the Ilm'; Central Bavarian: Pfahofa an da Uim) is a municipality in Bavaria, Germany, capital of the district Pfaffenhofen.

As of a press release in October 2011 from the UN-backed annual International Awards for Liveable Communities (LivCom), Pfaffenhofen an der Ilm was saluted by judges for the quality of its environmental best practice.

[3] Historians believe that monks from Ilmmünster Abbey built the Pfaffenhöfe near Altenstadt in the north of the city, in the 8th century.

The motorcycle speedway track run by the club MSC Pfaffenhofen[7] was demolished to make way for the sports park.
