John Ulrich Collins (7 July 1868 – 16 July 1943) was a New Zealand cricketer who played six first-class matches: one for Nelson in 1884–85 and five for Canterbury between 1892–93 and 1895–96. As a teenager, he had also appeared in a minor match for a Wellington XXII[sic] that had much the worse of a draw against a ten-man Australians side in 1886–87.
Collins acted as wicket-keeper in three of his Canterbury matches, although all three of his dismissals came in one game, versus Auckland in January 1894. In his final appearance, for Canterbury against New South Wales in December 1895, he bowled for the only time in first-class cricket, taking the wicket of Frank Ridge in the first innings.
His nephew David Collins played 53 first-class games, while his brother William Collins played two.
