Ewen John Chatfield (born 3 July 1950 in Dannevirke) is a former cricketer who played 43 Tests and 114 One Day Internationals for New Zealand. A medium-pace bowler, his chief weapon was his accuracy, giving him economical bowling figures, although he occasionally would come in for punishment in the late stages of limited overs matches due to a lack of variation in his line and length.
