John Thomas Hearne (3 May 1867 – 17 April 1944) (known as Jack Hearne, J. T. Hearne or Old Jack Hearne to avoid confusion with J. W. Hearne to whom he was distantly related) was a Middlesex and England medium-fast bowler. His aggregate of 3061 first-class wickets is the greatest for any bowler of medium pace or above, and his 257 wickets in 1896 is the tenth highest total on record. In 1891, 1896, 1898, 1904 and 1910 Hearne headed the first-class bowling averages.
