Karlskoga Municipality (Karlskoga kommun) is a municipality in Örebro County in central Sweden. Its seat is located in the city of Karlskoga. Other localities include Valåsen och Labbsand, Kortfors, Linnebäck and Villingsberg.

In 1940 the whole municipality, including its non-urban areas, got the title of a city. These titles were abolished in 1971.
