George Sargeant Cox (1 November 1877 – 25 October 1945) was a Jamaican cricketer who captained the Jamaican national side in his only first-class appearance. He later served as an umpire in several first-class matches featuring Jamaica.
Cox had earlier appeared for Jamaican sides against two visiting English teams – one during the 1901–02 season, led by Richard Bennett, and another during the 1904–05 season, led by Viscount Brackley (later the 4th Earl of Ellesmere). He only match at first-class level came in August 1905, against Trinidad at Sabina Park, Kingston. He took the wickets of N. F. Hart and J. Wilson in Trinidad's first innings, finishing with 2/24 from six overs, and the wicket of Sydney Smith in its second, taking 1/24 from eleven overs. While batting, Cox came in sixth in Jamaica's first innings, making 18 runs before being caught by Percy Cox (unrelated) off the bowling of J. A. Romeo. In the second innings, he opened the batting with Francis Wilson, making 13 before again being dismissed by Romeo, this time caught by Trinidad's Wilson (who Cox had earlier dismissed).
