Wyn Hoop (born Winfried Lüssenhop) is a former German singer who began his career in the early 1950s when he formed a jazz band called the Capitellos, who toured and worked on radio before disbanding in 1958. As a soloist, he first performed under the name Fred Lyssen before adopting the professional name Wyn Hoop.
Hoop recorded several successful German cover versions of English-language hits (such as "Are You Lonesome Tonight?") before joining forces in 1962 with Finnish singer Pirkko Mannola, with whom he recorded a number of popular tracks. From 1964, Hoop began recording with Austrian singer Andrea Horn, who he had married in 1961. In 1978, they retired from showbusiness.
