William Austin Horn (1841–1922) was an Australian mining magnate, pastoralist, politician, author, sculptor and philanthropist. Somewhat eccentric, in 1892 he was the donor of a copy of Antonio Canova's Venus, Adelaide's then controversial first public statue, which is still on display on North Terrace, Adelaide. Horn also built Wairoa, Aldgate, known for its magnificent gardens and captured in a watercolour by William Tibbits.
