Nikolay Alekseyevich Gulyayev (Russian: Николай Алексеевич Гуляев, born 1 January 1966) is a former speed skater, considered among the world's best in the 1980s.

Gulyayev debuted with a 5th place in the tournament won by Dutchman Hein Vergeer and impressed with a 2nd-place finish on the 1,500 metres.

In January, he won the European Championships in Trondheim, in front of Michael Hadschieff and Hein Vergeer.

His samalog World Record of 159.356 stood for 4 years before being broken by Johann Olav Koss at the same venue.

His performance at the World Championships in Heerenveen put him in first place on the Adelskalender, the all-time allround speedskating ranking, displacing his compatriot Viktor Shasherin, until, at the 1988 Winter Olympics, Austrian skater Michael Hadschieff took over first place, followed a few days later by Eric Flaim from the United States.

After those Olympics, Gulyayev found himself incapable of competing at the top level of international allround speed skating, so he switched his focus to the shorter sprinting distances.
