The Newfoundland Standard Time Zone (NST) is a geographic region that keeps time by subtracting 3½ hours from Coordinated Universal Time (UTC).

NST is used only in Canada, and there only by the province of Newfoundland and Labrador. Officially, the island of Newfoundland, plus its offshore islands, is the only part of the province that uses NST; Labrador, the mainland portion, officially uses Atlantic Standard Time. However, the southeastern tip of Labrador unofficially uses NST because it is more closely tied economically to the island than it is to the remainder of Labrador.

NST is known as Newfoundland Daylight Time (NDT) during daylight saving time, and has one hour added to make it 2½ hours behind UTC (UTC -2.5).
