Utladalen (or Utladal) is a valley in the municipality of Årdal in Sogn og Fjordane county, Norway. It stretches north from Øvre Årdal into the neighboring municipality of Luster. The Avdalen and Fardalen valleys branch off of the main Utladalen valley.
Utladalen is Norway's deepest valley. The main valley, when measuring from Øvre Årdal is long and is surrounded by dozens of mountain peaks that are all more than in height. From Øvre Årdal, a comfortable walking road has been constructed, funded by voluntary contributions. The road passes through Vetti and crosses the Utla river on four spectacular bridges. The walking path ends at one of Norway's tallest waterfalls, Vettisfossen.
Since Utladalen is considered to be unique in Norway and internationally, the Utladalen Landscape Protection Area was established along with the adjacent Jotunheim National Park in 1980 and covers about . It includes both the valley and areas that extend both westward and northward to Jotunheim National Park, and eastward to lake Tyin.
