The Fredrik Church (Swedish: Fredrikskyrkan) is located in Karlskrona, Blekinge Län, southern Sweden.

Situated on Stortorget, the main square in the city centre,[1] The Fredrik Church is included within the Karlskrona UNESCO World Heritage Site.

The Fredrik Church was built in the baroque style after a design by Nicodemus Tessin the Younger.

[2] The carillon is housed in the south tower, and there are 35 bells, which were installed in 1967 by the Bergholtz Bellfoundry [sv].

The 1854 pulpit is in a neoclassical style by the design of architect Johan Adolf Hawerman; it predates the altar.
