Nord-Aurdal is a municipality in Oppland county, Norway. It is part of the traditional region of Valdres. The administrative centre of the municipality is the village of Fagernes.

The parish of Nordre Aurdal was established as a municipality on 1 January 1838 (see formannskapsdistrikt). The area of Nordre Etnedal was transferred from Nord-Aurdal to the neighboring municipality of Etnedal on 1 January 1894.

The municipality is served by Fagernes Airport, Leirin. In Nord-Aurdal, there is an alpine skiing center called Valdres Alpinsenter.

The Old Norse form of the name was Aurardalr. The first element is the genitive case of an old river name Aur (now called Bøaelva) and the last element is dalr which means "valley" or "dale". The old river name is derived from aurr which means "gravel". The name was changed from Nordre- to Nord- Aurdal in the early 20th century. Both nordre and nord mean "north" (more specifically, "nordre" means "northern"), so the name Nord-Aurdal means "(the) northern (part of) Aurdal". (The parish of Aurdal was divided in 1805.)

The coat-of-arms is from modern times. They were granted by royal decree on 20 December 1985. The arms show three blue flowers of the species Gentiana nivalis (or Snow Gentian) on a yellow background. The flowers, which are locally known as "the blue eyes of Christ", grow abundantly in the area. Three flowers were chosen to represent the three main settlements of the municipality: Aurdal, Fagernes, and Leira. This type of flower only opens in sunlight and heat, so it was chosen to symbolize being open and positive.
