The County of the City of Aberdeen, also informally known as 'Aberdeen Corporation', 'The Corporation of Aberdeen', 'Corporation of the City of Aberdeen' or 'Aberdeen City Council', was established in 1900. In 1975 it was abolished under the 1973 Local Government (Scotland) Act and merged with Bucksburn, Dyce, Newhills, Old Machar, Peterculter and the Stoneywood areas of the county of Aberdeen, and the Nigg area of the county of Kincardine to form City of Aberdeen District Council.
