Bielefeld (German pronunciation: [ˈbiːləfɛlt] ) is a city in the Ostwestfalen-Lippe region in the north-east of North Rhine-Westphalia, Germany. With a population of 342,952, it is also the most populous city in the administrative region (Regierungsbezirk) of Detmold and the 18th largest city in Germany.

The historical centre of the city is situated in the Ravensberg Basin north of the Teutoburg Forest hill range, but modern Bielefeld extends across the range and further south into the flat Westphalian Basin. The city is situated on the Hermannsweg, a hiking trail that runs for 156 km along the ridges of the Teutoburg Forest.

Bielefeld is home to a significant number of internationally operating companies, including Dr. Oetker, DMG Mori (former Gildemeister), Möller Group, Goldbeck and Schüco. It has a university and several technical colleges (Fachhochschulen). Bielefeld is also known for the Bethel Institution.
