George Barton Rock (born 24 May 1936) is a former Barbadian cricketer who played eight matches of first-class cricket for Barbados between 1961 and 1969.
George Rock was a fast bowler who played for Barbados at a time when the leading Barbadian fast bowlers were the West Indies Test opening pair Wesley Hall and Charlie Griffith. In his first match for Barbados, against Trinidad in 1960-61, he took 6 for 63 in the first innings. The next season he took 5 for 86 and 4 for 8 when Barbados beat Jamaica by an innings. After 1961-62 he did not play for Barbados again until 1968-69, when Hall and Griffith were touring Australia. That season he was one of the most successful bowlers in the Shell Shield, with 18 wickets at an average of 16.05, including 3 for 80 and 6 for 18 against Trinidad.
Rock studied radio announcing in New York City in 1965. He represented the US in the annual match against Canada in 1964. He obtained a coaching certificate in England and returned to New York in 1969 to coach cricket.
