The Trondheim Fjord or Trondheimsfjorden (pronounced [ˈtrɔ̂nː(h)æɪmsˌfjuːɳ]), an inlet of the Norwegian Sea, is Norway's third-longest fjord at 130 kilometres (81 mi) long. It is located in the west-central part of the country in Trøndelag county, and it stretches from Ørland Municipality in the west to Steinkjer Municipality in the north, passing the city of Trondheim on its way. Its maximum depth is 617 metres (2,024 ft), in the channel between Orkland Municipality and Indre Fosen Municipality.
The largest islands in the fjord are Ytterøya and Tautra; the small island of Munkholmen is located near the harbor of Trondheim; and there are several islands at the entrance of the fjord. The narrow Skarnsundet is crossed by the Skarnsund Bridge. The part of the fjord to the north of the strait is referred to as the Beitstadfjorden. The main part of the Trondheimsfjord is ice-free all year; only Verrasundet, a long and narrow fjord branch in the northern part of the fjord, might be ice covered in winter. The Beitstadfjorden might also freeze over in winter, but only for a few weeks.
