Borisoglebsky (Russian: Борисоглебский; Finnish: Kolttaköngäs; Norwegian: Skoltfossen) is a rural locality (a Posyolok) in Pechengsky District of Murmansk Oblast, Russia.

The village is located beyond the Arctic Circle, at a height of 95 meters above sea level on the Paatsjoki River.

In June 1968, Boris Gleb was the venue for the largest Soviet display of aggression against Norway since the Second World War.

The Soviet army stopped 30 meters away, aiming their tanks at Norwegian military installations.

The confrontation lasted until 10 June, when Soviet forces retired from the border area.[why?
