Müswangen is a municipality in the district of Hochdorf in the canton of Lucerne in Switzerland. Since 1 January 2009, it has been part of the municipality of Hitzkirch.
Müswangen is first mentioned in 924 as Milizwaga. It is a combination of two words müssen - "mosses" and wangen - (foot of) so it doesn't really translate.
Müswangen has an area of 4.5 km2 (1.7 sq mi). Of this area, 70.9% is used for agricultural purposes, while 24.2% is forested. Of the rest of the land, 4.7% is settled (buildings or roads) and the remainder (0.2%) is non-productive (rivers, glaciers or mountains). The municipality is located on the west slope of the Lindenberg mountain.
On 21 May 2006 an attempt to merge Hitzkirch and the surrounding 10 municipalities failed, when five of the eleven voted against the merger. A less ambitious merger was then proposed and accepted, with the municipalities of Gelfingen, Hämikon, Mosen, Müswangen, Retschwil and Sulz joining Hitzkirch on 1 January 2009.
