Billund Municipality (Danish: Billund Kommune) is a kommune in the centre of the Jutland Peninsula in Denmark. Formerly the municipality belonged to Ribe County. The new, merged municipality covers an area of 540.18 km², and has a total population of 27,119 (2024). Its mayor is Stephanie Storbank, a member of Venstre (Liberal Party) political party.[2] The site of its municipal council is the town of Grindsted, which is the largest town in the municipality followed by the city of Billund.
On 1 January 2007, as a result of Kommunalreformen ("The Municipal Reform" of 2007), approved by the lawmakers in Folketinget 16 June 2005, and, after the signature by the head of state, published in Lovtidende, and being in effect from 26 June 2005, the new municipality was formed. The old Billund municipality was combined with the former Grindsted Municipality and the part of Billund Airport that was located in Give Municipality. The first election to the municipal council in the new municipality (and the regional council in the new region) was held 15 November 2005, which was the regular date of elections once every four years.
