William Edward Mattinson (1 April 1836 – 11 August 1911) was a politician in the colony of South Australia.
He was born in London, and emigrated with his parents William Edward Mattinson and his wife Mary to South Australia, arriving in April 1837 and settling on Kangaroo Island. They moved to Port Lincoln around 1840, then settled in Port Adelaide in 1843.[1]
William worked as a builder and contractor in the Port Adelaide area.
He was a member for Port Adelaide in the South Australian House of Assembly from April 1881 to April 1890.[2] His colleague for the first term was David Bower and George Hopkins for the second. He stood unsuccessfully for the seat in 1890 and again in 1896.
He was an active member of the Victoria Lodge of the Order of Oddfellows, and Chairman of the Port Adelaide Football Club from 1902 to 1910, when failing health forced him to resign.
