Charles Flinders Hursthouse (7 January 1817 – 22 November 1876) was an English-born settler in New Zealand in the early 1840s. He wrote a number of books and pamphlets encouraging emigration to New Zealand, and gave lectures in England on the same subject on behalf of the New Zealand Company. In an 1869 pamphlet he advocated for the federation of the five eastern Australian colonies and New Zealand to form an Australasian republic.
