The RAF launched three Typhoon aircraft from its Quick Reaction Alert along with two pairs of Tornadoes from air bases in Lossiemouth and Coningsby.
A Voyager tanker - an air-to-air refueling aircraft - was also deployed from a base in Brize Norton to support the mission.
The number of Russian jets involved in the incident is unclear.
It is believed they were Tupolev Tu-95 Bears, which are used both as strategic bombers and long-range maritime patrol planes.
An RAF spokesperson said: “We can confirm that RAF Quick Reaction Alert Typhoon aircraft were launched today from RAF Lossiemouth and RAF Coningsby.”
“This was a routine response to Russian aircraft approaching UK air space and was coordinated with several other NATO allies.”
