Llanharan () is a village and community in the county borough of Rhondda Cynon Taf, Wales. As a community Llanharan takes in the neighbouring settlements of Bryncae, Brynna, Llanilid, Peterston-super-Montem and Ynysmaerdy. Llanharan thrived during the British Industrial Revolution, with several tin and coal mines in the location providing employment to the town's residents. With the decline of heavy industry in the South Wales Coalfield, Llanharan has been in economic decline, though its proximity to the M4 motorway offers its residents easy commutable access to most of South Wales.
Historically part of Glamorgan, the most recognisable features of Llanharan are its historic town square, Llanharan House and Church of St Julius and Aaron.
