Sir Peter Wyche (1628 – c. 1699) was an English diplomat and translator.
He was one of the sons of Sir Peter Wyche and brother of Sir Cyril Wyche. He was educated at Exeter College, Oxford (matriculated 1643), Queens' College, Cambridge (BA 1645) and Trinity Hall, Cambridge (MA 1648) and was admitted to the Inner Temple in 1649. He was knighted in 1660. In May 1663 he was elected a Fellow of the Royal Society.[1]
He was English Ambassador to Russia in 1669 and then immediately after to Poland in 1669–1670.[2]
He died in London circa 1699. He had married Isabella, daughter of Sir Robert Bolles, Bart, of Scampton, Lincolnshire. His grandson Cyril Wyche also became Envoy Extraordinary and Minister Plenipotentiary to Russia and was created a baronet in 1729 (see Wyche baronets).
