The bowhead whale (Balaena mysticetus) is a species of the family Balaenidae, in suborder Mysticeti, and genus Balaena, once thought to include the right whale.

A stocky dark-colored whale without a dorsal fin, it can grow 14 to 18 m (46 to 59 ft) in length. This thick-bodied species can weigh from 75 to 100 tonnes (74 to 98 long tons; 83 to 110 short tons). They live entirely in fertile Arctic and sub-Arctic waters, unlike other whales that migrate to low latitude waters to feed or reproduce. The bowhead was also known as the Greenland right whale or Arctic whale. American whalemen called them the steeple-top, polar whale, or Russia or Russian whale. The bowhead has the largest mouth of any animal.

The bowhead was an early whaling target. The population was severely reduced before a 1966 moratorium was passed to protect the species. Through conservation efforts, the bowhead population has since recovered and is now rated "Least Concern" on the IUCN Red List of Threatened Species.

Carl Linnaeus first described this whale in the 10th edition of his Systema Naturae (1758). Seemingly identical to its cousins in the North Atlantic, North Pacific and Southern Oceans, they were all thought to be a single species, collectively known as the "right whale", and given the binomial name Balaena mysticetus.

Today, the bowhead whale occupies a monotypic genus, separate from the right whales, as was proposed by the work of John Edward Gray in 1821. For the next 180 years, the family Balaenidae was the subject of great taxonometric debate. Authorities have repeatedly recategorized the three populations of right whale plus the bowhead whale, as one, two, three or four species, either in a single genus or in two separate genera. Eventually, it was recognized that bowheads and right whales were in fact different, but there was still no strong consensus as to whether they shared a single genus or two. As recently as 1998, Dale Rice, in his comprehensive and otherwise authoritative classification, Marine mammals of the world: systematics and distribution, listed just two species: B. glacialis (the right whales) and B. mysticetus (the bowheads).
