Tredegar railway station was a station on the Sirhowy Railway. It served the town of Tredegar. The station was near the southern edge of Bedwellty Park.

The station was opened on 19 June 1865 by the Sirhowy Railway after the conversion of the Sirhowy Tramroad to a standard gauge railway.

The line south from Tredegar closed to goods traffic on 30 April 1969,

On 17 December 1902 a fatal accident occurred when a train from Tredegar to Nantybwch with 9 loaded coal wagons and a brake van was stopped on the incline of 1 in 42 near Nantybwch. The driver uncoupled the engine for adjustments; on recoupling he backed the engine on to the wagons, setting them in motion back down the hill until they reached Tredegar, about 1½ miles distant, where a disastrous collision occurred.

The route has been reused by the modern A4048 road;
