Aberdare is an industrial town in the county borough of Rhondda Cynon Taff in the traditional county of Glamorgan, in south Wales, situated (as the name implies) at the confluence of the Dar and Cynon rivers. The population at the (1991) census was 31,619. It is 4 miles S.W. of Merthyr Tydfil and 24 miles N.W. of Cardiff.

Aberdare was a constituency of the House of Commons of the Parliament of the United Kingdom from 1918 to 1983. It elected one Member of Parliament (MP) by the first past the post system of election. Although the constituency name was no longer used after 1983, the constituency underwent only very minor boundary changes losing just 7 voters to the Rhondda seat and gianing under 3,000 from Brecon and Radnor (2095) and Neath (1126) constituencies.
