State Children's Aid Association or State Children's Association was a British children's rights organization established in 1896 to support the welfare of pauper children. The association was active from 1897 until 1937. Its headquarters were in London, at 61 Old Broad Street, E.C. in 1899 and at 117 Picadilly, W.1. in 1923. The main objects of the association were to obtain individual treatment for children under the guardianship of the State, and to obtain for the State further powers of control over neglected children. It agitated for better treatment of the many thousand orphan and other children dependent upon the public and advocated for doing away with barrack schools.
