Robert Gordon Grevett (24 November 1914 – 5 March 2004) was an English cricketer.
Grevett was a right-handed batsman who bowled right-arm off break.
He was born at Eastbourne, Sussex.
Grevett made a single first-class appearance for Sussex against Oxford University at The Saffrons, Eastbourne, in 1939.
Oxford University won the toss and elected to bat, scoring 178 in their first-innings.
In response, Sussex made 169 in their first-innings, with Grevett, who batted at number three, being dismissed for a duck by David Macindoe.
Oxford University made 324 in their second-innings, leaving Sussex with a target of 334 to win.
However, Sussex could only make 277 in their second-innings chase, with Grevett once again dismissed for a duck, this time off the bowling of Algernon Marsham.
This was his only major appearance for Sussex.
He died at Chertsey, Surrey, on 5 March 2004.
His uncle, William Grevett, also played a single first-class match for Sussex.
