Tafarnaubach is a village situated on the Sirhowy River in the county borough of Blaenau Gwent, in south-east Wales. Located within the historic boundaries of Monmouthshire it lies about two miles from Tredegar town centre.
To the south of the village lies a small Country Park, Parc Bryn Bach, while the northern part of the district is dominated by the Tafarnaubach Industrial Estate. The village is overlooked by Mynydd Llangynidr, a location that was popular for illegal bare-knuckle boxing mountain fights during the late 19th century due to its proximity to three county borders.
