John Nyren (15 December 1764 – 30 June 1837) was an English cricketer and author.
Nyren made 16 known appearances in first-class cricket from 1787 to 1817.
Latterly, he achieved lasting fame as the author of The Cricketers of My Time, which was first published in 1832 as a serial in a periodical called The Town; and was then included in The Young Cricketer's Tutor, published in 1833 by Effingham Wilson of London.
Nyren's collaborator in the work was Charles Cowden Clarke.
