On 1 January 1964, the part of Hamarøy located on the south side of the Sagfjorden and west of the Veggfjellan mountain (population: 77) was transferred to neighboring Steigen Municipality.

On the same date, the Tysnes and Molvik farms (population: 33) was transferred from Hamarøy to the neighboring Tysfjord Municipality.

[13] On 21 January 2011, the national government approved a resolution to add a co-equal, official Sami language name for the municipality: Hábmer.

It is called Hábmer when it is spelled alone, but it is Hábmera suohkan when using the Sami language equivalent to "Hamarøy Municipality".

The official blazon is "Azure, a lynx statant guardant argent" (Norwegian: I blått en stående sølv gaupe).

The lynx has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used.

This means the arms have a blue field (background) and the charge is a depiction of a 9,000-year-old rock carving of the outlines of two swans.

[1] Lakes in the municipality include Fjerdvatnet, Forsanvatnet, Forsvatnet, Kaldvågvatnet, Kilvatnet, Livsejávrre, Makkvatnet, Reinoksvatnet, Rekvatnet, Rotvatnet, Sandnesvatnet, Skilvatnet, Šluŋkkajávri, and Strindvatnet.

Hamarøy is dominated by small fjords, pine, birch, and aspen woodland and forest, and coastal mountains.

The wettest season is autumn and early winter, while April - June is the driest, indicating an oceanic climate.

Here is a list of people who held this position (incomplete list): While Hamarøy has a low population density, it sees some traffic during the summer months as the main road connection to Svolvær and the Lofoten islands runs through Hamarøy and its administrative centre, Oppeid.

The Hamsun literature festival was founded in 1982 and takes place in Hamarøy during the first week of August every second year.
