John Sheppard (also Shepherd, c. 1515 – December 1558) was an English composer of the Renaissance.
Sheppard was probably born around 1515, judging from his statement in 1554 that he had been composing music for twenty years. Nothing certain is known about his early life. The first undoubted sighting of him occurs when he was probably in his later twenties, as informator choristarum at Magdalen College, Oxford. He served in this capacity during 1541-2 and again from 1544-8.Sheppard left Magdalen College in March 1548 and next appears in a list of the Gentleman of the Chapel Royal who sang at the funeral of King Edward VI in August 1553; he may have joined the chapel directly after his departure from Magdalen, but, because of a gap in Chapel Royal records from 1547, this is not certain. He presumably remained active at the chapel up to the year of his death.
