Stephen Royston Barwick (born 6 September 1960) is a former Welsh cricketer.
Barwick was a right-handed batsman who began his career a right-arm medium-fast bowler, before adding variation in the form of changes of pace and off cutters, with his restyled bowling being termed by fellow professionals like Andrew Caddick as the "slowest seam bowling around".
Playing for Glamorgan for 18 seasons, he took 768 wickets in all formats of the game.
Married to Margaret Barwick, father to Michael, Kathryn and Jessica.
