A winter festival, winter carnival, snow festival, or frost fair is an outdoor cold weather celebration that occurs in wintertime.

Winter festivals are popular in D climates (see Köppen climate classification) where winter is particularly long or severe, such as Siberia, Scandinavia, Canada and the northern United States. Most winter carnivals involve traditional winter pursuits such as dog sledding, ice hockey, ice carving, skating, skiing, and snow carving.
