The maritime boundary between Norway and Russia was delimited by three separate agreements, and the overlapping extended continental shelf claims in the Arctic Ocean have yet to be delimited. The first maritime boundary agreement was signed on 15 February 1957 and defined the territorial seas of Norway and the Soviet Union in the mouth of the Varangerfjord as well as a short section of continental shelf. Fifty years later, on 11 July 2007, Norway and Russia replaced the 1957 line with a slightly longer but still incomplete maritime boundary, comprised of six turning points and spanning roughly 39 nautical miles.

Following decades of negotiation, on 15 September 2010 the parties defined their continental shelf and exclusive economic zone boundaries between Norway’s Svalbard Archipelago and Russia’s Novaya Zemlya Archipelago. It began at the final point of the 2007 line and extended for 906 nautical miles.

The total length of delimited maritime boundary between Norway and Russia now spans 945 nautical miles.
