The Llancaiach Branch railway line was a mineral branch line in Glamorganshire, South Wales.

It was designed by Isambard Kingdom Brunel and built on the standard gauge. It opened in 1841 from a junction with the Merthyr line immediately south of Abercynon. It was intended to be horse worked, and included a self-acting rope-worked inclined plane near the junction. The collieries were slow to use the line, preferring their customary use of a tramroad and the Glamorganshire Canal, and the value of the line was diminished when the Taff Vale Extension line, an east-west connecting line belonging to the Newport, Abergavenny and Hereford Railway, intersected it and cut off the colliery connections, and the line became dormant.
