What is the name of the sea between Norway and Russia?

The sea between Norway and Russia is the Barents Sea.

The Barents Sea is a marginal sea of the Arctic Ocean, lying off the northern coasts of both countries. Norway borders its western and southern shores, while Russia borders much of its southern and eastern side. Important nearby landmarks include Norway’s North Cape, Russia’s Kola Peninsula, Svalbard, Franz Josef Land, and Novaya Zemlya.

The sea is named after Willem Barentsz, the Dutch navigator who led late-16th-century expeditions seeking a northern route to Asia. Russian maps formerly used names such as Murman Sea. Despite its Arctic location, the southern Barents Sea often remains ice-free in winter because warm Atlantic water flows in with the North Atlantic Drift.

A common mix-up is the Norwegian Sea, which lies west of the Barents Sea and connects it to the wider Atlantic. The North Sea is much farther south, between Great Britain and mainland Europe. The Barents Sea is also notable for its shallow continental shelf, rich fisheries, and major strategic importance to Russia and Norway.
