The Scaddan Ministry was the 11th Ministry of the Government of Western Australia and was led by Labor Premier John Scaddan. It succeeded the First Wilson Ministry led by Ministerialist Frank Wilson on 7 October 1911 after the decisive result of the state election held four days earlier, which had produced the State's first majority Labor government.
The 1914 election produced a one-seat majority for the Labor government, but the disappearance of Joseph Gardiner and his replacement by a Liberal candidate in a by-election, as well as a Labor member becoming an Independent and refusing to support the Government, enabled Wilson to call for a vote of no confidence in the government. On 27 July 1916, the Scaddan Ministry resigned and the Second Wilson Ministry was sworn in.
