Kautokeinoⓘ (Norwegian), Guovdageaidnu (Northern Sami), or Koutokeino (Kven)[3] is the administrative centre of Kautokeino Municipality in Finnmark county, Norway.

The European route E45 runs through the village on its way from the town of Alta as it heads south.

From 1882 to 1883 Sophus Tromholt ran a Northern Lights observatory here as a part of the first international polar year.

He was the first to photograph Kautokeino's Sami as character portraits with full names, not as tourist props or race examples.

The Tromholt Collection became part of Unesco's Norwegian document heritage register in 2012, according to a display integrated with the facade of Stein Rokkan Building at the University of Bergen.
