The coat of arms, granted in 1978, displays the so-called virgineagle (or harpy), which was the heraldicanimal of the Cirksena family, a local clan providing East Frisian chieftains during the Middle Ages. The acorns in the arms are symbols of the city of Aurich and the six-pointed spurs are symbols of Norden. The blazon is: "party per pale Azure and Gules, a harpy gardant Argent, above shoulders two six-pointed mullets Argent, below wings two acorns inverted Argent".
The former coat of arms, granted in 1950, shows a goldenoak tree, representing the Upstalsboom, a tree outside the city of Aurich under which free Frisians gathered for their yearly council meetings. Its blazon is: "Gules, an oak tree Or, on a hill Or at base".
