Røyrvik (Norwegian) or Raarvihke (Southern Sami) is a municipality in Trøndelag county, Norway.

[8] On 13 June 2014, the national government approved a resolution to add a co-equal, official Southern Sami language name for the municipality: Raarvihke.

It is called Raarvihke when it is spelled alone, but it is Raarvihken tjïelte when using the Sami language equivalent to "Røyrvik Municipality".

The official blazon is "Azure, a cross crosslet argent" (Norwegian: I blått et korset sølv kors).

The charge has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used.

This design is a common decoration on the pottery, hand-made articles, and traditional pewter embroidery found in the area.

The highest point in the municipality is the 1,511.98-metre (4,960.6 ft) tall mountain Jetnamsklumpen, located inside Børgefjell National Park.

The municipal council (Kommunestyre) of Røyrvik is made up of 11 representatives that are elected to four year terms.

Here is a list of people who have held this position:[34] From 1911 until World War I, mining explorations were conducted in the Gjersvik areas.
