Hallstahammar Municipality (Swedish: Hallstahammars kommun) is a municipality in Västmanland County in central Sweden. Its seat is located in the town of Hallstahammar.

In 1971 "old" Hallstahammar (with the status of a köping since 1943) was amalgamated with parts of the dissolved Kolbäck rural municipality to form the present unitary municipality..

The municipal slogan is "Bo hos oss" ("Live with us"), which reflects the ambition of the present municipal leadership to boost population figures.
