Tjørnuvík (Danish: Tjørnevig) is the northernmost village on Streymoy in Sunda Municipality, Faroe Islands.

[citation needed] The town uses the Stakkur sea stack for sheep grazing, accessed by cable car.

[1] The Risin og Kellingin sea stacks are visible across the Sundini strait.

A 5 km (3 mi) single-lane dead-end road (route 594) from Haldórsvík is the only way to reach Tjørnuvík.

Tourists clogged the road in summer, before a traffic control system improved conditions in 2022.
