Blaenau Ffestiniog railway station serves the slate mining town of Blaenau Ffestiniog, Wales, and is the passenger terminus of the Conwy Valley Line from Llandudno Junction. Transport for Wales Rail operate through services to Llandudno Junction and Llandudno. The station is a joint station with the narrow gauge Ffestiniog Railway, which operates primarily tourist passenger services to Porthmadog throughout most of the year. A feature of the standard gauge service is the availability on trains and buses of the popular "Gwynedd Red Rover" day ticket.

Blaenau Ffestiniog is a town in Gwynedd, Wales. Once a slate mining centre in historic Merionethshire, it now relies much on tourists, drawn for instance to the Ffestiniog Railway and Llechwedd Slate Caverns. It reached a population of 12,000 at the peak development of the slate industry, but fell with the decline in demand for slate. The population of the community, including the nearby village Llan Ffestiniog, was 4,875 at the 2011 census: the fourth most populous in Gwynedd after Bangor, Caernarfon and Llandeiniolen. The population not including Llan is now only about 4,000.
