The Hårsfjärden, or Horsfjärden (Swedish pronunciation: [ˈhɔ̂ʂːˌfjæːɖɛn]),^[1] is a fjard off the Baltic Sea near Stockholm, Sweden. About 20 kilometres (12 mi) long, it has surface area of 61.5 square kilometres (23.7 sq mi).^[2] It is the location of three Swedish naval bases: Märsgarn, Muskö, and Berga.

It was the location of the Hårsfjärden incident, during October 1–13, 1982, in which Swedish forces appeared to have trapped a foreign submarine, believed to be Soviet, but the submarine escaped.^[3]

Three Swedish destroyers were sunk in the Hårsfjärden in an explosion on 17 September 1941, during World War II. The three destroyers sunk at a naval base on the fjord were Göteborg, Klas Horn and Klas Uggla. Göteborg and Klas Horn were later salvaged and returned to service, while Klas Uggla was scrapped.^[4][5]
