William John Hurst (c.1829 – 29 September 1886) was a 19th-century Member of Parliament in New Zealand and Mayor of Auckland. He was born in Berwick-upon-Tweed. In January 1868, Hurst stood in a by-election in the City of Auckland East electorate for the Auckland Provincial Council. He defeated Charles Davis 163 votes to 107. Hurst remained on the provincial council until the abolition of provincial government in 1876. Hurst represented the Auckland West electorate from the 1879 election to 1881, and then the Waitemata electorate from the 1881 election to 1886 when he died.
