Kirkelandet) was Fosna or Fosen (Old Norse: f�lgsn) which means "hiding place" (here 'hidden port'). It was also often named Lille Fosen ("the small Fosen") to distinguish it from the island Storfosna ("the big Fosen") in �rland.
Before 1877, the name was written Christianssund, from 1877-1888 it was spelled Kristianssund, and since 1889 it has had its present spelling, Kristiansund.
Before the introduction of postal codes in Norway in 1968, it was easy to confuse the name Kristiansund with Kristiansand in the south. It was therefore obligatory to always add an N (for north) to Kristiansund (Kristiansund N) and an S (for south) to Kristiansand (Kristiansand S)
