Hogmanay ([ˌhɔɡməˈneː] hog-mə-nay) is the Scots word for the last day of the year and is synonymous with the celebration of the New Year (Gregorian calendar) in the Scottish manner. It is normally followed by further celebration on the morning of New Year's Day (1 January) or, in some cases, 2 January—a Scottish Bank Holiday.

The origins of Hogmanay are unclear, but may be derived from Norse and Gaelic observances. Customs vary throughout Scotland, and usually include gift-giving and visiting the homes of friends and neighbours, with special attention given to the first-foot, the first guest of the new year.
