Thennes (French pronunciation: [tɛn]) is a commune in the Somme department in Hauts-de-France in northern France.

Thennes is situated 12 miles (19 km) southeast of Amiens, on the D11a road and bordered to the north and northwest by the river Luce, and to the west by the river Avre.

Known as Tanes in 1128, because of the tanneries in the area, it became known as Thannes then Thannes-Thennes in 1507.

The history of Thennes has always been closely linked with that of the neighbouring commune of Berteaucourt-les-Thennes.
