The Östergötland class were a class of destroyers built for the Swedish Navy in the late 1950s. They were smaller and less capable than the preceding Halland class and were decommissioned in 1982. The class was to be the last destroyers to be built by Sweden in the 20th century. They were sometimes referred to as Light destroyers.

Notes

1. In the case of the Södermanland, unlike her sister ship Hälsingland, Eriksbergs Mekaniska Verkstad just built the hull, with completion and fitting out done by Kockums Mekaniska Verkstads AB. The reasons for this are unclear, though it may possibly have been part of a work share agreement.
