Ruabon Moors are an area of upland moorland in Wales to the west of Ruabon and Wrexham. They lie partly within Wrexham county borough and partly within Denbighshire.
In the northern part of the moors are the areas known as Minera Mountain and Esclusham Mountain. Further south are Ruabon Mountain and Eglwyseg Mountain. In the west the moors reach their greatest height at Cyrn-y-Brain (565m, 1854 feet above sea level).
To the north and north-east, the moors are bounded by Minera Limeworks and the Clywedog valley. In the east they slope down to the villages of Rhosllannerchrugog and Ruabon. There are several small reservoirs in this area. At the southern edge of the moors the cliffs of Eglwyseg Rocks overlook the River Dee and the Vale of Llangollen. On the western side there are more cliffs at World's End while the Horseshoe Pass separates the moors from Llantysilio Mountain. Llandegla Forest, a large conifer plantation, covers the north-western side.
Ruabon Moors are part of a Site of Special Scientific Interest and hold a wide variety of plant and animal life. Large parts of the moors are covered with heather. Where there are outcrops of limestone on the surface a number of scarce plants can be found such as prickly sedge, dark red helleborine and rigid buckler-fern.
