Rayner John Blitz (born 25 March 1968 at Watford, Hertfordshire), was a cricketer who played five first-class matches and one List A match for Somerset in 1986.^[1]

A diminutive wicketkeeper and right-handed batsman who had played for Essex's second eleven in 1985, Blitz was signed to cover for an injury to Trevor Gard, Somerset's regular wicketkeeper.^[2] He took eight catches in his five games and played for Somerset's second eleven across the summer. But the county was looking for a wicketkeeper who could make reliable runs as the long-term successor to Gard, and signed Neil Burns from Essex for the 1987 season. Blitz was released by Somerset at the end of the 1986 season.^[2]

Blitz did not play first-class cricket again, though he played for Derbyshire's second eleven and for Dorset in the Minor Counties.
