John Grey "Jack" Taiaroa (16 September 1862 – 31 December 1907), of Ngāi Tahu descent, was a New Zealand rugby union player. A halfback, he played nine matches for the New Zealand national team in 1884—the warm-up in Wellington and all eight matches of the tour of New South Wales; New Zealand played and won all eight games. There were no test matches on the tour, as there was not yet an Australian national team, and would not be until 1903.
Born in Otakou, the son of Hori Kerei Taiaroa, a New Zealand Member of Parliament, Taiaroa played school-boy rugby for Otago Boys' High School and then for the Otago provincial side. He went on to set a national record in the long jump and represent Hawke's Bay in first-class cricket during the 1890s as an attacking batsman.
