HNoMS Valkyrien, HNoMS Valkyrjen (in Norwegian the prefix KNM is used) has been the name of several ships in the Royal Norwegian Navy. Most of them have been in some way connected to the Royal Norwegian Navy's torpedo boats. The name honours the valkyries of Norse mythology. It has also been said that the ships have been given this name in honour of all women. Some of the ships:
