Holum is a former municipality that was located in the old Vest-Agder county in Norway. The 116-square-kilometre (45 sq mi) municipality existed from 1838 until its dissolution in 1964. The administrative centre was the village of Krossen where Holum Church is located. The municipality was located in the present-day municipality of Lindesnes in what is now Agder county.
The parish of Holme was established as a municipality on 1 January 1838 (see formannskapsdistrikt law). During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, most of Holum (population: 1,127) was merged with the town of Mandal and the municipality of Halse og Harkmark to form a new, larger Mandal municipality. The remainder of Holum (the Stubstad and Svalemyren areas, with a population of 9) was merged into the neighboring municipality of Søgne.
The municipality (originally the parish) was named after the old Holme farm (Old Norse: Holeimr), since that is the location of Holum Church. The name is a combination of the word hol or hull meaning "hole" and the word heimr meaning "home". The spelling of the name was changed from Holme to Holum in 1911.
All municipalities in Norway, including Holum, are responsible for primary education (through 10th grade), outpatient health services, senior citizen services, unemployment and other social services, zoning, economic development, and municipal roads. The municipality was governed by a municipal council of elected representatives, which in turn elected a mayor.
The municipal council (Herredsstyre) of Holum was made up of representatives that were elected to four year terms. The party breakdown of the final municipal council was as follows:
