Captain Samuel Albert White (20 December 1870 – 19 January 1954) was a wealthy Australian racehorse owner, soldier, explorer, conservationist and amateur ornithologist. He was born in Fulham, South Australia and eventually died there. He fought in the South African War 1900–1903, reaching the rank of captain, which title he continued to use throughout his life. He made several private ornithological collecting expeditions across remote areas of Australia, to Alice Springs (1913), Musgrave and Everard Ranges (1914), Cooper Creek (1916), Nullarbor Plain (1917-1918), Finke River (1921), and Adelaide to Darwin and return (1922), on behalf of Gregory Mathews.
White was a foundation member of the South Australian Ornithological Association (SAOA) in 1899, and served as its president for several periods between 1904 and 1944. He was also a foundation member of the Royal Australasian Ornithologists Union (RAOU) in 1901, and served as its president 1914–1916.
