Glyndŵr was one of six districts of Clwyd between 1974 and 1996.
It was formed on 1 April 1974, under the Local Government Act 1972, from parts of the administrative counties of Denbighshire and Merionethshire.
From Denbighshire came the boroughs of Denbigh, Llangollen and Ruthin, the rural districts of Ceiriog and Ruthin and the parishes of Llangollen Rural and Llantysilio, formerly in Wrexham Rural District. From Merionethshire came the Edeyrnion Rural District.
The district was named after Owain Glyndŵr, who lived in Glyndyfrdwy for a while.
On 1 April 1996 the district was dissolved, with parts going to each of the three principal areas of Denbighshire, Powys and Wrexham.
