Until 1 January 2007 Thyborøn-Harboøre was a municipality (Danish, kommune) in the former Ringkjøbing County on the west coast of the Jutland peninsula in west Denmark.
The municipality covered an area of 42 km2, and had a total population of 4,690 (2005).
To the east are the waters of Nissum Bredning, a large body of water connected to the North Sea, which lies directly to the west of the former municipality.
The Nissum Bredning is the westernmost part of the Limfjord (Limfjorden), a shallow sound that separates the island of Vendsyssel-Thy to the north of the former municipality from the rest of the Jutland Peninsula.
This created a municipality with an area of 510 km2 and a total population of 22,760 (2005).
