John Cooper (around 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. He was also music teacher to William Lawes.

Among Cooper's works are fantasias, suites and other works for viols and violins, and two collections of songs, Funeral Teares (1606) and Songs of Mourning: Bewailing the Untimely Death of Prince Henry (1613). He also penned the treatise on composition, Rules how to Compose.
