Archibald Henry Peake (15 January 1859 – 6 April 1920) was an Australian politician. He was Premier of South Australia on three occasions: from 1909 to 1910 for the Liberal and Democratic Union, and from 1912 to 1915 and 1917 to 1920 for its successor, the Liberal Union. He had also been Treasurer and Attorney-General in the Price-Peake coalition government from 1905 to 1909. Early life and career Peake's family migrated from Chelsea, London in 1862, initially settled in Victoria, before moving to South Australia two years later.
