Gullspång Municipality (Gullspångs kommun) is a municipality in Västra Götaland County in western Sweden. Its seat is located in the towns of Gullspång and Hova.
The present municipality was formed through the amalgamation of the former entities of Amnehärad, Hova and part of Visnum. The name was taken from the locality Gullspång.
The southern part of the municipality contains the northern part of Swedish national park Tiveden.
The two main towns are Hova and Gullspång. The central administration is placed in Hova, thus constituting the municipal seat, but there are also offices in Gullspång. Because of the rivalry between Gullspång and Hova the municipality prefers to call them the "two main localities" ("huvudtätorter").
