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.
On 7 October 1911, the Governor, Rt Hon Baron Gerald Strickland, designated 6 principal executive offices of the Government under section 43(2) of the Constitution Acts Amendment Act 1899. The following ministers were then appointed to the positions, and served until the Ministry was reconstituted on 23 November 1914 following the 1914 election.
