Værøy is an island municipality in Nordland county, Norway. It is part of the traditional district of Lofoten. The administrative centre of the municipality is the village of Sørland on the main island of Værøya. The other village in Værøy is Nordland. Most of the residents live in the Sørland area surrounding the main harbor. The old Værøy Lighthouse sits at the end of that harbor.

The 19-square-kilometre (7.3 sq mi) municipality is the 351st largest by area out of the 356 municipalities in Norway. Værøy is the 347th most populous municipality in Norway with a population of only 728. The municipality's population density is 39.1 inhabitants per square kilometre (101/sq mi) and its population has decreased by 4.3% over the previous 10-year period.

The Old Norse form of the name was Veõrøy. The first element is veõr which means "weather" (here referring to harsh weather and the exposed and unsheltered position of the island). The last element is øy which means "island". Historically, the name has been spelled Værø.

Tourist attractions include:

• Sportfishing for cod, coalfish, and halibut is practiced here.
• Turstien is a floodlit track which was opened in 1999. The surface is suitable for bikers, prams, and wheelchairs.
• Breivika is situated on the road between Sørland and Nordland, and is the location of the Skarsursanden beach. From the main road there is a signposted path going up Breivikdalen.
• Heia has views of the island. It can be reached via a step path called Bjørka, or by following the tarred road up Rømdalen. About halfway there is an old eagle trapping site.
• Eagle trapping is a tradition peculiar to the Veõrøy islanders. They caught eagles with their bare hands. Ancient sites can still be seen, at Rømdalen, for instance.
• Gjerdeheia forms a vast and completely flat plateau on top. It can be reached from Breiviksdalen by turning left at the end of the valley or following the path going up Rømdalen and turning right before passing Hornet.
• Nordlandsnupen is Veõrøy's highest mountain. One must reach it by walking up Breiviksdalen and turning right at the end of the valley.
• Mollbakken in Nordland consists of smoothly ground round stones. Here, many burial sites from the Viking Age have been found.
• Old Veõrøy Church in Nordland is the oldest church in Lofoten, built around 1740. The altarpiece dates back to about 1714 and features alabaster figures made in England in 1430.
• Nordlandshagen - the Garden of Nordland - is a popular area for the outdoor life. The midnight sun can be seen here from May 30 to July 13.
• Mostad is located in the south. The mountainside more or less hangs right over the old, abandoned village of Mostad. This is where the puffin dog originated. Often people will walk from Nordlandshagen.
• Norwegian Lundehund or Puffin dog is one of Norway's seven breeds of dogs, and the rarest one. It has an extra toe, is small, and very agile. Puffin dogs were used solely for the puffin hunt and because the hunt was of such great importance to the islanders, this race of dogs managed to survive in Veõrøy.
• Sanden is a beach with a 400-metre (1,300 ft) tall wall of rock towers over the spot, making it incredibly warm on fine summer days. Access is only by boat.
