Tovdal (historic: Lille Topdal) is a former municipality in the old Aust-Agder county in Norway.

The administrative centre of the municipality was the village of Hillestad where the Tovdal Church is located.

[1][3] The municipality (originally the parish) was first named "Lille Topdal" after the Topdalen valley (Old Norse: Þofnardalr).

On 3 November 1917, a royal resolution changed the spelling of the name of the municipality to simply Tovdal, dropping the prefix lille and changing the p to a v.[5] While it existed, this municipality was responsible for primary education (through 10th grade), outpatient health services, senior citizen services, unemployment, social services, zoning, economic development, and municipal roads.

[6] The municipal council (Herredsstyre) of Tovdal was made up of 13 representatives that were elected to four year terms.
