The Ecclesiastical Commissioners Act 1847, sometimes called the Bishopric of Manchester Act 1847, is an act of the Parliament of the United Kingdom with the principal purpose of delegating to the Ecclesiastical Commissioners for England the power to put forward a scheme to create the Diocese of Manchester. The Ecclesiastical Commissioners scheme containing the precise arrangements for the diocesan changes was put forward to Queen Victoria at Osborne House in the Isle of Wight, on 10 August 1847, where it was assented to in Chambers.
