The name is derived from the Old Norse word bjúgr which means "bent" or "crooked", probably referring to the bent/crooked path of the local fjord, the Bjugnfjorden.

The official blazon is "Azure, a rudder Or" (Norwegian: I blått et gull ror).

The rudder 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 blue color in the field and the rudder design symbolizes the historical importance of fishing in the municipality.

The highest point in the municipality was the 492.5-metre (1,616 ft) tall mountain Seksortklumpen.
