Tjørnuvík (Danish: Tjørnevig) is the northernmost village on Streymoy in Sunda Municipality, Faroe Islands. As of the 2006 census, the population has a total of 71 people.
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 5sigfig=1NaNsigfig=1 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.[2] [3] Funding was approved for prestudies for a tunnel.[4]
