Nikolay Sergeyevich Morilov is a Russian cross-country skier who has been competing since 2004. He won two medals at the FIS Nordic World Ski Championships with a silver in the team sprint (2007) and a bronze in the individual sprint (2009).

The FIS Nordic World Ski Championships 2007 took place 22 February – 4 March 2007 in Sapporo, Japan. It was the second time this city has hosted these championships, having previously done so in the 1972 Winter Olympics. Sapporo was selected as venue by vote at the 43rd FIS World Congress in Portorož, Slovenia, on 6 June 2002. It also marked the third time the championships were hosted outside Europe in a year that did not coincide with the Winter Olympics; it was the first championship held in Asia. The ski jumping team normal hill event was not held, as it had been in 2005.
