is a historical province (landskap) in the northern part of Sweden. It is bordered (clockwise from the north) by Swedish Lapland, Västerbotten, the Gulf of Bothnia, Medelpad and Jämtland. Prince Nicolas of Sweden is Duke of Ångermanland. The name is derived from the Old Norse anger, which means "deep fjord" and is a reference to the deep mouth of the Ångerman River (Ångermanälven). In earlier times the province was known, in medieval Latin, as Angermannia.
