Slagelse Municipality (Danish: Slagelse Kommune, pronounced [ˈslɛːjl̩sə kʰoˈmuːnə]) is a kommune in Region Zealand on the west coast of the island of Zealand in Denmark. The municipality covers an area of 571 km². The municipality borders Kalundborg Municipality to the north, Sorø Municipality to the north-east, Næstved Municipality to the south-east and connects to Nyborg Municipality via the Great Belt Bridge.

The main city and the site of the municipal council is the city of Slagelse. The mayor was earlier John Dyrby Paulsen, a member of the Social Democratic political party.

The municipality include the inhabited islands of Omø, Agersø and Glænø, as well as the uninhabited islands of Sprogø, Østerfed, Stenfed, Ormø, Fuglehøj, Sandholm, Kidholm and Fugleholm.

On 1 January 2007 the former Slagelse municipality was, as the result of Kommunalreformen ("The Municipal Reform" of 2007), merged with Hashøj, Korsør, and Skælskør municipalities to form an enlarged Slagelse municipality.
