Haltdalen (historically: Holtaalen or HoltÃÂ¥len) is a former municipality in the old Sør-Trøndelag county, Norway. The municipality existed from 1838 until 1972 when it was merged with àlen Municipality to become the present-day HoltÃÂ¥len Municipality in Trøndelag county. The administrative centre of the municipality was the village of Haltdalen where the Haltdalen Church is located.

The parish of Holtaalen (later re-named Haltdalen) was established as a municipality on 1 January 1838 (see formannskapsdistrikt law). In 1841, the western part of the municipality (population: 1,272) was separated to become the new Singsaas Municipality. This left Holtaalen with 1,885 residents. Then in 1855, the southeastern part of Holtaalen Municipality (population: 1,487) was separated to become the new Aalen Municipality. This left Holtaalen Municipality with 809 residents. In 1917, the spelling of the name was changed to HoltÃÂ¥len Municipality. In 1937, the name was changed from HoltÃÂ¥len Municipality to Haltdalen Municipality. Starting in the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1972, ÃÂ len Municipality (population: 1,944) was merged with the neighboring Haltdalen Municipality (population: 778) and together they formed the new HoltÃÂ¥len Municipality (bringing back the name HoltÃÂ¥len, the historic name for Haltdalen Municipality).
The municipality (originally the parish) was first named Holtaalen. The first element of the name comes from the local river , a side branch of the larger Gaula River. The last element is which means "narrow river channel" (like an eel). On 21 December 1917, a royal resolution enacted the 1917 Norwegian language reforms. Prior to this change, the name was spelled Holtaalen with the digraph "aa", and after this reform, the name was spelled HoltÃÂ¥len, using the letter ÃÂ¥ instead.
On 15 October 1937, a royal resolution changed the name of the municipality to Haltdalen, effective 1 January 1938. The first element of the new name came from the same river name as before. The last element comes from which means "valley" or "dale". The municipality kept this name until 1972 when the municipality was merged with the neighboring ÃÂ len Municipality to form the new HoltÃÂ¥len Municipality, resurrecting the old name of the municipality that was used before 1937.
