Cölbe (German pronunciation: [ˈkœlbə] ⓘ) is a municipality in Marburg-Biedenkopf district in Hesse, Germany.

Cölbe's municipal area lies on the southern edge of the Burgwald, a low mountain range and part of the Hessisches Bergland (Hessian Highland), and borders directly on the university city of Marburg to the south.

The namesake constituent community is found on a bow in the river Lahn where it bends from its mainly easterly flow to a mainly southerly one.

As of municipal elections on 14 March 2021, seats on the municipal council are apportioned thus: The Institute for Theoretical Geodesy in Bonn has ascertained that the European Union's centre point after the 2004 expansion lies at the coordinates 50°51′10″N 8°46′43″E / 50.85278°N 8.77861°E / 50.85278; 8.77861 (Geographical centre of the European Union (Bonn calculation)).

Newer efforts delving into this question, however, have yielded different results, putting the EU's centre point most recently at Gadheim in Bavaria.
