William Fox, English-New Zealand lawyer and politician, 2nd Prime Minister of New Zealand (born 1812)

Sir William Fox was the second premier of New Zealand and held that office on four occasions in the 19th century, while New Zealand was still a colony. He was known for his confiscation of Māori land rights, his contributions to the education system, and his work to increase New Zealand's autonomy from Britain. He has been described as determined and intelligent, but also as bitter and "too fond" of personal attacks. Different aspects of his personality are emphasised by different accounts.

The prime minister of New Zealand is the head of government of New Zealand. The incumbent prime minister, Christopher Luxon, leader of the New Zealand National Party, took office on 27 November 2023.
