Losnedahl is a Norwegian surname. It is a compound of two Norwegian elements: Losna, the name of a place or farm in Norway, and dahl, a variant of dal meaning "valley." Thus, the name likely originally referred to someone who lived near or came from a valley associated with Losna.
The element -dahl is a common suffix in Norwegian surnames, often added to place names or topographic features to denote a valley. Surnames of this type were typically adopted in the 19th century or earlier when patronymic naming customs were replaced by fixed family names in Norway.
Given the rarity of the name, it is likely concentrated in specific regions of Norway, possibly linked to the area around Lake Losna in the Gudbrandsdalen valley. In adoptice of fixed surnames among rural populations, farm names were a common source.
