William Prudhoe JP (14 January 1832 – 29 April 1908) was Mayor of Christchurch, New Zealand, for 1892.

He received his education at a public school and then undertook an apprenticeship as a builder and mason.

He married Anne (Annie) Adamson in 1855 and had two boys in England; the second one (Joseph) was born in Durham.

[16][17] Prudhoe announced his intention to run for mayor and for a long time, it was expected that he was going to be returned unopposed.

George Bonnington, another city councillor, received a petition to stand for election that he acceded to.

[12] Prudhoe died on 29 April 1908 at his home in Montreal Street in the central city.
