William Hunter Reynolds (1 May 1822 – 1 April 1899) was a 19th-century businessman and Member of Parliament in Dunedin, Otago region, New Zealand.

He represented that electorate, from the third council named City of Dunedin, until the abolition of provincial government in 1876.

[1] In 1893 Reynolds was at the centre of a drama that led to the passing of the Women's suffrage bill into law.

Premier Seddon had expected to stop the bill in the upper house, but found that one more vote was needed.

Thomas Kelly, a new Liberal Party councillor had left himself paired in favour of the measure, but Seddon obtained his consent by wire to change his vote.
