Neskaupstaður is a town located on the fjord Norðfjörður on the eastern side of Iceland. It is part of the municipality of Fjarðabyggð and, as of 2011, it has a population of 1,437.
It suffered severe depopulation in the 1990s, but this has been reversed as a result of the building of an aluminum smelter and a new hydroelectric power-plant in East Iceland.
Neskaupstaður joined Eskifjörður and Reyðarfjörður in 1998 to form the new municipality of Fjarðabyggð ("fjords-settlement").
The 2002 Icelandic movie Hafið (The Sea) was filmed almost entirely in and around Neskaupstaður.
The other villages composing the municipality are: Eskifjörður (1,043 inh.), Fáskrúðsfjörður (662 inh.), Mjóifjörður (35 inh.), Reyðarfjörður (1,102 inh.) and Stöðvarfjörður (203 inh.).
