Plas Madoc is a housing estate and former electoral ward near[1] Acrefair, in the Cefn community in Wrexham County Borough, Wales.

[2] It is located seven miles to the south-west of Wrexham, and contains The Land adventure playground, and a community-run[3] leisure centre with a swimming pool.

[9] The furnace had an annual output of 300 short tons (270 tonnes) in 1711, and between 1757 and 1761 (or potentially earlier), there could have been a site for Coke smelting.

[9] The site was developed by the Lloyd family of Plas Madoc, with their descendants later establishing the Acrefair or New Ruabon Iron Works on the estate in around 1817.

The centre was closed and earmarked for demolition by Wrexham Council on 27 April 2014[11] citing the cost to maintain and modernise its facilities, but was re-opened under community management on 6 December 2014.
