Gustaf Adam von Nolcken, also rendered in English sources as Gustavus Adam von Nolcken, was a Swedish diplomat and civil servant. He served as Sweden's envoy extraordinary at the Court of St James's from 1764 to 1793, a tenure spanning the American Revolutionary War, the reign of Gustav III of Sweden, and the opening years of the French Revolutionary Wars. He was elected a Fellow of the Royal Society in 1777, came into contact with American diplomats including John Adams, and was later appointed president of the Göta Court of Appeal, although he remained in England.
