Kárášjohka (Northern Sami) or Karasjok (help·info) (Norwegian) or Kaarasjoki (Finnish) is a village and municipality in Finnmark county, Norway. The administrative centre of the municipality is the village of Karasjok.Karasjok is a Norwegianized form of the Sámi name Kárášjohka. The meaning of the first element is unknown and the last element is johka which means "river".
The municipality was part of the old Kistrand municipality until 1866. The name of the municipality was Karasjok until 1990, when it was changed to Kárášjohka-Karasjok. It was the third municipality in Norway to get a Sami name. In 2005 the name was again changed, such that either Kárášjohka or Karasjok can be used.
The coat-of-arms is from modern times. They were granted on 27 June 1986. The three flames are chosen as a symbol for the importance of fire to the local (nomadic) Sami people. The fire brings both heat and thus survival during the harsh winters, but it is also a major threat, both in the tents as well as in the large pine forests. The fire is also the point around which people gather and it is a guard against dangers. The flag contains three flames also because Kárásjoga-Karasjok is a place where three peoples live: the Sami, Norwegians, and Kvens.
