The Nærøyfjord (or Nærøyfjorden) is a fjord in the municipality of Aurland in Sogn og Fjordane, Norway. The narrow fjord is a branch of the large Sognefjord, and it is featured on the "Norway in a Nutshell" daytrips for tourists. The 18-kilometre (11 mi) long fjord is only 500 metres (1,600 ft) wide in some parts.
The river Nærøydalselvi flows down the valley Nærøydalen into the fjord at the village of Gudvangen, near the highway E16. The village of Bakka and the Bakka church are located on the west shore of the fjord.
Since 2005, the Nærøyfjord has been listed as a UNESCO World Heritage Site. It has also been rated by the National Geographic Society as the world's number one natural heritage site along with the Geirangerfjord.
