Olofström, previously Holje by, is a locality in Blekinge County, Sweden with 7,327 inhabitants in 2010.

Today the automobile industry, dominated by Volvo Cars, is the largest employer in Olofström.

Immediately west of Olofström lies Halen [sv], a nature reserve covering 809 hectares (2,000 acres) of land and water, making it one of the largest protected areas in Blekinge.

The area is also rich in biodiversity, with old-growth forests and habitats for a variety of bird species, including ospreys and loons.

A rebuild was completed in 1962 under the guidance of architects Hanna and Roy Victorson in Karlshamn.
