Lyngen (Northern Sami: Ivgu; Kven: Yykeä[5]) is a municipality in Troms county, Norway.

Then on 1 January 1875, a small part of Lyngen (population: 7) was transferred to the neighboring Balsfjord Municipality.

On 1 January 1902, the Sørfjorden area (population: 1,139) was separated from Lyngen to form the new Sørfjord Municipality.

On 21 June 1929, a royal resolution was issued that divided the large municipality of Lyngen into three parts.

[9] On 1 January 2020, the municipality became part of the newly formed Troms og Finnmark county.

[11] The municipality (originally the parish) is named after local Lyngen fjord (Old Norse: Lygnir).

The official blazon is "Argent, a horse forcene regardant sable" (Norwegian: I sølv en oppreist svart hest med hodet vendt bakover).

The silver or white color in the field symbolizes the importance of the sea and fishing industry and the horse represents the local agriculture.

The line was first established during the German occupation of Norway and the main purpose was to halt a Soviet invasion.

[17] During the Cold War the Norwegian Army continued to reinforce the Lyngen lined against a possible invasion from the east.

The municipal centre is the village of Lyngseidet, a pretty settlement on an isthmus that almost cuts the peninsula in the middle.
