Gautelisvatnet (Northern Sami: Guovdelisjávri) is a lake that is located on the border of Norway and Sweden. The Norwegian side lies in the municipality of Narvik in Nordland county and the Swedish side lies in Gällivare Municipality in Norrbotten County. The 17.67-square-kilometre (6.82 sq mi) lake has a dam on the northern end and the water is used for hydropower. After the dam was built, the lake grew and merged with the lake Vannaksvatnet to the south. The lake Unna Guovdelisjávri lies just to the east of this lake.
