Beilen is a town in the Dutch province of Drenthe. It is a part of the municipality of Midden-Drenthe, and lies about 16 km south of Assen. The old Reformed church is the only remaining truly old building; a large fire destroyed a major part of Beilen in 1820.

Beilen has a railway station - Beilen railway station.

The biggest employers in Beilen are the former DOMO milk powder factory and the psychiatric hospital GGZ Drenthe. The village is also home to a large distribution centre for the Jumbo supermarket chain. Beilen is also visited by many tourists, as it is located between many forests and National Reserves. Each August the so-called "Wende-aovends" take place in Beilen, featuring activities for children in the shopping center and showcases by local artists at night.

Until 1998, Beilen was a separate municipality.

There are four primary schools: Beatrix, GA de Ridder, De Eshorst, and Harm Smeenge. There are two secondary schools: Dr. Nassau College and CS Vincent van Gogh.
