Cross-country skiing is a form of skiing where skiers rely on their own locomotion to move across snow-covered terrain, rather than using ski lifts or other forms of assistance. Cross-country skiing is widely practised as a sport and recreational activity; however, some still use it as a means of transportation. Variants of cross-country skiing are adapted to a range of terrain which spans unimproved, sometimes mountainous terrain to groomed courses that are specifically designed for the sport.

Modern cross-country skiing is similar to the original form of skiing, from which all skiing disciplines evolved, including alpine skiing, ski jumping and Telemark skiing. Skiers propel themselves either by striding forward (classic style) or side-to-side in a skating motion (skate skiing), aided by arms pushing on ski poles against the snow. It is practised in regions with snow-covered landscapes, including Northern Europe, Canada, Russia and regions in the United States. Competitive cross-country skiing is one of the Nordic skiing sports. Cross-country skiing and rifle marksmanship are the two components of biathlon, ski-orienteering is a form of cross-country skiing, which includes map navigation along snow trails and tracks.

The word ski comes from the Old Norse word "skíð" which means stick of wood.Skiing started as a technique for traveling cross-country over snow on skis, starting almost five millennia ago with beginnings in Scandinavia. It may have been practised as early as 600 BCE in Daxing'anling, in what is now China. Early historical evidence includes Procopius' (around CE 550) description of Sami people as skrithiphinoi translated as "ski running samis". Birkely argues that the Sami people have practiced skiing for more than 6000 years, evidenced by the very old Sami word čuoigat for skiing.Egil Skallagrimsson's 950 CE saga describes King Haakon the Good's practice of sending his tax collectors out on skis. The Gulating law (1274) stated that "No moose shall be disturbed by skiers on private land." Cross-country skiing evolved from a utilitarian means of transportation to being a world-wide recreational activity and sport, which branched out into other forms of skiing starting in the mid-1800s.
