Budal is a former municipality in the old Sør-Trøndelag county, Norway. The 335-square-kilometre (129 sq mi) municipality existed from 1879 until its dissolution in 1964. It encompassed the Bua and Ena river valleys in the south-central part of the what is now Midtre Gauldal Municipality in Trøndelag county. The administrative center of Budal was the village of Enodden where Budal Church is located.

Prior to its dissolution in 1964, the 334.8-square-kilometre (129.3 sq mi) municipality was the 260th largest by area out of the 689 municipalities in Norway. Budal Municipality was the 674th most populous municipality in Norway with a population of about 545. The municipality's population density was 1.6 inhabitants per square kilometre (4.1/sq mi) and its population had decreased by 7% over the previous 10-year period.

The parish of Budal was established as a municipality in 1879 when it was separated from the large Støren Municipality. Initially, Budal Municipality had a population of 585.

During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, a large municipal merger took place. Budal Municipality (population: 529) was merged with Singsås Municipality (population: 1,554), Soknedal Municipality (population: 1,916), and Støren Municipality (population: 2,296) to form the new Midtre Gauldal Municipality.

The municipality (originally the parish) is named after the old Budalen farm (Old Norse: Buadalr) since the first Budal Church was built there. The first element is the name of the local river Bua. That name is the same as the word bua which refers to a "place where people live". The last element is dalr which means "valley" or "dale". Historically, the name of the municipality was spelled Budalen. On 3 November 1917, a royal resolution changed the spelling of the name of the municipality to Budal, removing the definite form ending -en.

The Church of Norway had one parish (sokn) within Budal Municipality. At the time of the municipal dissolution, it was part of the Støren prestegjeld and the Gauldal prosti (deanery) in the Diocese of Nidaros.

The municipality was located in the Gauldalen valley. Kvikne Municipality (in Hedmark county) was to the south, Singsås Municipality was to the east, Støren Municipality was to the north, and Soknedal Municipality was to the west. The highest point in the municipality was the 1,235-metre (4,052 ft) tall mountain Stiftsvardhøgda.

While it existed, Budal Municipality was responsible for primary education (through 10th grade), outpatient health services, senior citizen services, welfare and other social services, zoning, economic development, and municipal roads and utilities. The municipality was governed by a municipal council of directly elected representatives. The mayor was indirectly elected by a vote of the municipal council. The municipality was under the jurisdiction of the Frostating Court of Appeal.
