John Cooper (c. 1570 – 1626), also known as Giovanni Coprario or Coperario, was an English composer, viol player and lutenist. He changed his name in the early 17th century. It is often said he did this after a visit to Italy, though there is no evidence he had been to the country. From 1622 he served and may have taught the Prince of Wales, for whom he continued to work upon his succession as Charles I. His longtime patron was Edward Seymour, Earl of Hertford, for whom he taught William Lawes.
