Húsavík is a town in Norðurþing municipality on the north coast of Iceland on the shores of Skjálfandi bay with 2,237 inhabitants. Income is derived from tourism and fishing, as well as retail and small industry. Until recently, Húsavík was the export harbour for silica that was extracted from nearby lake Mývatn.
Húsavík has become a centre of whale watching in Iceland due to whales of different species that frequently enter the bay. The Húsavík Whale Museum is located in the downtown by the harbour.
