Mo is a former municipality in Telemark county, Norway.
The parish of Mo was established as a municipality January 1, 1838 (see formannskapsdistrikt).
The municipality (originally the parish) was named after the farm Mo (Old Norse Mór), since the first church was built there. The name is identical with the word mór m 'heath, moor'.
