William Alfred Fitzherbert (1842 – 2 February 1906) was the first Mayor of Lower Hutt, New Zealand, from when Lower Hutt became a borough in 1891 to 1898. He was an engineer and farmer in New Zealand.
William Fitzherbert was born in London in 1842, a son of William Fitzherbert. The family followed his father to Wellington about 1846. Fitzherbert was educated in Wellington, at Sydney Grammar School, and at Canterbury University College. He was an engineer with the Wellington Provincial Council and with the Hutt County Council. He farmed in the Wanganui district, and then in the Hutt Valley and in Hawke’s Bay.
In 1876, he married the adopted daughter of George Waterhouse, and they had five daughters and four sons. He died suddenly in Lower Hutt on 2 February 1906 of heart failure.
In 2011, plaques were installed on 13 boulders at the Hutt Recreation Ground commemorating the first 13 mayors.
