Mid Glamorgan County Council (Welsh: Cyngor Sir Morgannwg Ganol) was the upper-tier authority for the Welsh county of Mid Glamorgan between its creation in 1974 and its abolition in 1996.

[1] Mid Glamorgan County Council was abolished in 1996 under the Local Government (Wales) Act 1994, with the districts in the area being reorganised to become unitary authorities taking over the functions previously performed by the county council.

[1] The chief executive was solicitor, Tom Vivian Walters, who had worked for Glamorgan County Council since 1943.

[1] Squire continued as leader of the council for 15 years, until retiring in 1989 at the age of 83.

Because of the dominance of the Labour Party on the council, it was sometimes referred to as a "Squirearchy".
