Name

The municipality (originally the parish) is named after the Beiar Fjord (Old Norse: Beðir or Beðinn). The meaning of the name is uncertain. It may be derived from the plural form of the word beðr which means "bedding" (in the sense of a "river bed". Another option is that it is the past participle of the word biðja which means "to pray" or "to ask".^[7] Historically, the name of the municiaplity was spelled Beieren. On 6 January 1908, a royal resolution changed the spelling of the name of the municipality to Beiara.^[8] This spelling, however, was not well-liked. On 19 August 1908 (a few months later), another royal resolution changed the spelling of the name of the municipality to Beiarn.^[9]

Coat of arms

The coat of arms has been used in Beiarn since 1988. The blazon is "Vert, a pine tree uprooted Or" (Norwegian: I gull en furu på grønn bunn). This means the arms have a green field (background) and the charge is a pine tree. The pine tree has a tincture of Or which means it is commonly colored yellow, but if it is made out of metal, then gold is used. The pine tree was chosen to symbolize the mighty pine forests for which Beiarn has historically been well-known. This is mentioned both by Petter Dass' "Nordlands Trompet" and in Lars Hess Bing's "Description of the Kingdom of Norway, the Isles of Iceland and the Faroe Islands, as well as Greenland". There are remains of giant pine trees that are likely over one thousand years old. The green color of the field was chosen to represent the lush green forests and the gold/yellow color was chosen because the forest is "worth its weight in gold" for the municipality. The arms were designed by Erik Gabrielsen, who was a cultural consultant in Beiarn municipality. In 1995, the municipality applied to have the arms formally approved for use by the National Archives of Norway, but they were not approved because it did not meet the heraldic standards for coats of arms in Norway. The National Archives told the municipality that they can use the unapproved arms in some circumstances, but they cannot be put on a flag, road sign, or public buildings.^{[10][11][12][13]}
