Cardiff Council, formally the County Council of the City and County of Cardiff is the governing body for Cardiff, one of the principal areas of Wales. The principal area and its council were established in 1996 to replace the previous Cardiff City Council which had been a lower-tier authority within South Glamorgan. Cardiff Council consists of 79 councillors, representing 28 electoral wards.

Cardiff City Council was the local government district authority that administered the city of Cardiff, capital of Wales, from 1974 until 1996. The district council replaced the pre-1974 county borough council. It was succeeded in 1996 by Cardiff Council.
