The Sognefjord or Sognefjorden, nicknamed the King of the Fjords, is the largest and deepest fjord in Norway. Located in Vestland county in Western Norway, it stretches 205 kilometres (127 mi) inland from the ocean to the small village of Skjolden in the municipality of Luster.

In physical geography, a fjord or fiord is a long, narrow sea inlet with steep sides or cliffs, created by a glacier. Fjords exist on the coasts of Antarctica, the Arctic, and surrounded landmasses of the northern and southern hemispheres. Norway's coastline is estimated to be 29,000 km (18,000 mi) long with its nearly 1,200 fjords, but only 2,500 km (1,600 mi) long excluding the fjords.
