Dinas station was built by the Festiniog Railway (FR). It was the first passenger station in Blaenau Ffestiniog, then in Merionethshire, now in Gwynedd, Wales. This station is not to be confused with Dinas some miles distant on the Welsh Highland Railway; nor is it to be confused with the Festiniog and Blaenau Railway's northern terminus in the centre of Blaenau Ffestiniog which was sometimes referred to colloquially as "Dinas".
