Torghatten is a granite dome on the island of Torget in Brønnøy Municipality in Nordland county, Norway. It is known for its characteristic hole, or natural tunnel, through its center. It is possible to walk up to the tunnel on a well-prepared path, and through it on a natural path.

On 6 May 1988, Widerøe Flight 710 from Namsos Airport to Brønnøysund Airport crashed into the side of the mountain, and all 36 passengers and crew died.

According to legend, the hole was made by the troll Hestmannen while he was chasing the beautiful woman Lekamøya. As the troll realized he would not overtake her, he released an arrow to kill her, but the troll-king of Sømna threw his hat into the arrow's path to save her. The hat turned into the mountain with a hole in the middle.

The tunnel is 160 metres (520 ft) long, 20 metres (66 ft) wide, and 35 metres (115 ft) high. It was formed during the Scandinavian ice age. Ice and water eroded the looser rocks, while the harder ones in the mountain top have resisted erosion.
