A snowdrift is a deposit of snow created by wind into a mound during snowstorms. They resemble sand dunes and are formed in a similar manner, namely, wind moving light snow and depositing it when the wind is slowed, usually against a stationary object.

Their impact on transportation is often as significant as heavy snowfall, such as during the Blizzard of 1977. Snow drifts are many times found along or on roads, as the crest of the roadbed or the furrows along the road create the disruption to the wind needed to shed its carried snow. In high mountain passes, a snow fence may be employed on the windward side of the road to intentionally create a drift before the snow-laden wind reaches the roadway.

Snow drifts commonly form on high ground, such as a plateau or hills.
