Dyrøy (Northern Sami: Divrráid suohkan) is a municipality in Troms county, Norway.

[4][5] The municipality is named after the island of Dyrøya, which is connected with the mainland with the modern Dyrøy Bridge.

On 1 January 1964, the parts of Tranøy Municipality located on the mainland (population: 382) were transferred to Dyrøy.

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

[9] The municipality (originally the parish) is named after the island of Dyrøya (Old Norse: Dýrøy) since the first Dyrøy Church was built there.

The official blazon is "Azure, a fox statant argent" (Norwegian: I blått en stående sølv rev).

This means the arms have a blue field (background) and the charge is a locally-bred platinum fox.

The fox has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used.
