Jan Vriend (born November 1938 in Benningbroek) is a Dutch classical music composer, conductor, organist and pianist. He lives in Gloucestershire, England, and has lived there since 1984.
Vriend studied at the Amsterdam Conservatory from 1960 to 1967, with Else Krijgsoman (piano), Anthon van der Horst and Jan Felderhof (music theory), and Ton de Leeuw (composition). During this period, he also studied electronic music with Gottfried Michael Koenig at the University of Utrecht.
Vriend won the Conservatoire of Amsterdam Prize for Composition (1967), the Schnittger Organ Prize (1966) for his composition Herfst (Dutch for "Autumn") and the Gaudeamus International Composers Award with Huantan in 1970.
As a conductor, Vriend has directed several choirs and instrumental ensembles which perform both early and contemporary music. Perhaps the best-known of these is the ASKO Ensemble, which he founded in 1965.
