The small village of Aberbeeg (from Welsh Aber-bîg 'mouth of the river Bîg') lies in both the county borough of Blaenau Gwent and Caerphilly County Borough Council in Wales, within the historic boundaries of Monmouthshire. It is part of the community of Llanhilleth. The two main tributaries of the Ebbw River, the Ebbw Fawr and Ebbw Fach converge at Aberbeeg. Nearby are the villages of Llanhilleth and Six Bells, where the former colliery allowed the whole community to thrive as part of the South Wales coalfield community.
