Ilmarinen was a Finnish Navy Panssarilaiva, Swedish Pansarskepp ("Armored ship"; a coastal defence ship by British classification). The unit was constructed at the Crichton-Vulcan shipyard in Turku, Finland, and named after the mythological hero Ilmarinen from the Finnish national epic, the Kalevala. Ilmarinen was the flagship of the Navy from 1 May 1933 until her sinking on 13 September 1941.
