Culemborg (Dutch pronunciation: [ˈkyləmbɔr(ə)x] ⓘ) is a municipality and a city in the centre of the Netherlands, in the province of Gelderland.

In Joan Blaeu's map of 1649, Culemborg remains entirely enclosed by walls behind its city moat-like encircling canals.

In the beginning of the 18th century, Culemborg effectively lost its independence as it was incorporated into the Nijmegen Quarter, although it regained some sovereign rights.

Close collaboration with inhabitants and experimental sustainable design has made the neighbourhood an international best practice.

The railway station also provides a bus hub, offering buses to the various neighbouring cities and villages (namely Buren, Beusichem and Nieuwegein).

Centraal Boekhuis, trading under CB since 2012, is the main distributor of books in The Netherlands and has been based in Culemborg since 1973.
