Fagersta Municipality (Fagersta kommun) is a municipality in Västmanland County in central Sweden. Its seat is located in the city of Fagersta.

The City of Fagersta (instituted in 1944) was in 1967 merged with Västervåla parish (which had been part of Surahammar Municipality since 1963). In 1971 it was transformed into a municipality of unitary type.

Localities

The municipal seat, Fagersta, is the only locality within the municipality with more than 200 inhabitants.

Another locality of note is Ängelsberg, a village located on Åmänningen Lake.

Politics of Fagersta

Fagersta is historically a left wing stronghold, with mostly a social democratic majority running the town, a trend only broken with a further left majority between 1998–2014. However, a rapid shift saw the right-leaning coalition narrowly win the 2022 Swedish general election vote in the municipality. The local elections still saw the Social Democratic-Left Party combination winning a combined majority of seats.
