Tokke is a municipality in Telemark county, Norway. It is part of the traditional region of Vest-Telemark. The administrative centre of the municipality is the village of Dalen. The municipality of Tokke was created on 1 January 1964 upon the merger of the two older municipalities of Lårdal and Mo. Located in Lårdal, Eidsborg Stave church is one of Norway's old stave churches.
The name originally belongs to the river running through the municipality. The Old Norse form of the river name must have been Þotka and it is related to the name of the lake Totak (which it comes from). The river name is probably derived form the Norse word þot meaning "roaring, rushing, or howling".
