Glaucous gull (Larus hyperboreus) is a huge gull, the world’s second largest. It breeds in the Northern Hemisphere’s Arctic areas and winters on the coasts of the Holarctic. The genus name derives from the Latin larus, which appears to have referred to a huge seabird or gull.

Burgomaster is an ancient English name for this species.
