William Henry Moore (16 October 1863 – 25 February 1956) was an Australian cricketer who represented both New South Wales and Western Australia at first-class level. From Maitland, New South Wales, Moore came from a large cricketing family, with his father, uncle, brother, and two of his nephews all playing first-class cricket for New South Wales. One of his nephews was Charlie Macartney, who later played Test cricket for the Australian national cricket team. Moore played all four matches for New South Wales in the 1893–94 Sheffield Shield, playing as a wicket-keeper. The second of these matches, against South Australia at the Sydney Cricket Ground, was played alongside his brother, Leon Moore, the only time the brothers played together at first-class level.
