Gevelsberg (German pronunciation: [ˈɡeːfl̩sˌbɛʁk] ⓘ; Westphalian: Gievelsbiärg) is a town in the district of Ennepe-Ruhr-Kreis, in North Rhine-Westphalia, Germany.

The archbishop of Cologne Engelbert II of Berg was killed on November 7, 1225 by his cousin Frederick of Isenberg in Gievilberch.

As a consequence, a monastery of atonement (German: Sühnekloster) was established at the place of Engelbert's death and became the origin of the settlement resulting in today's Gevelsberg.

Gevelsberg received its coat of arms (a brick gable on a green hill, and a cogwheel indicating its industry) by decree of the Prussian Department of the Interior in 1903.

In the most recent mayoral election was held on 13 September 2020, Jacobi was re-elected with 87.1% of votes, defeating Felix Keßler, who was endorsed by the CDU, Free Voters, The Greens, and FDP.
