Trevor David Pinnock (born 16 December 1946 in Canterbury, England) is a British harpsichordist and conductor.

He is best known for his association with the period-performance orchestra The English Concert, which he helped found and directed from the keyboard for over 30 years in baroque and classical music. He is a former artistic director of Canada's National Arts Centre Orchestra and founded The Classical Band in New York.

Since his resignation from The English Concert in 2003, Pinnock has continued his career as a conductor, appearing with major orchestras and opera companies around the world. He has also performed and recorded as a harpsichordist in solo and chamber music and conducted and otherwise trained student groups at conservatoires. Trevor Pinnock won a Gramophone Award for his recording of Bach's Brandenburg Concertos with the European Brandenburg Ensemble, an occasional orchestra formed to mark his 60th birthday.
