Lyngdal was established as a municipality on 1 January 1838. Austad and Kvås were separated from Lyngdal on 1 January 1909 but they were again merged with Lyngdal on 1 January 1964, together with the area of Spangereid west of Lenesfjorden.
It is a coastal municipality, and borders to the southeast Lindesnes municipality, Audnedal to the northeast, Hægebostad to the north, and Kvinesdal and Farsund to the west. Lyngdal declared township on 1 January 2001.
Major sources of revenue are wood processing, agriculture, and commerce. Tourism is also central to the community, with the beaches of Kvavik and Rosfjord being popular resorts during the summer.
