Primarily a fishing and farming community, Leka is the northernmost municipality in Trøndelag county.

On 1 January 1909, the southern mainland district of Leka (population: 881) was separated to form the new Gravvik Municipality.

The official blazon is "Gules, a winged claw Or" (Norwegian: I rødt en vinget gull klo).

This means the arms have a red field (background) and the charge is a wing and claw of an eagle.

The wing and claw design has a tincture of Or which means it is commonly colored yellow, but if it is made out of metal, then gold is used.

[1] Dated to the Viking Age, the burial mound Herlaugshaugen is one of the largest (in Norway) from that era.

The municipal council (Kommunestyre) of Leka is made up of 13 representatives that are elected to four year terms.
