Eric William Dempster, MBE (25 January 1925 – 15 August 2011), was a New Zealand cricketer who played in five Tests from 1953 to 1954.
A left-arm spinner and useful lower-order batsman, Dempster played for Wellington from 1947-48 to 1960-61. He made his Test debut in the Second Test against South Africa in Auckland in 1952-53, and toured South Africa the following season, playing in four of the five Tests. His best performance in Tests was in the Fourth Test in 1953-54 in Johannesburg, when he made 21 not out batting at number eight in the first innings then, when New Zealand followed on, he opened and top-scored with 47 in the second innings.
His best first-class bowling figures of 5 for 46 came in the match against Orange Free State at Bloemfontein in 1953-54, and he scored his only century, 105, for Wellington against Canterbury at Wellington in 1956-57.
