Bala Junction railway station was on the Ruabon to Barmouth line in southern Gwynedd, Wales.

During its operational life, Bala Junction served as an interchange station for the branch line train to Blaenau Festiniog, usually operated by small tank locomotives such as the 6400 Class 0-6-0PT and 5800 Class 0-4-2T tank locomotives.

These trains did not run beyond Bala Junction, instead returning north to the GWR station at Blaenau Festiniog.

These were used particularly when the branch line train was shunting in preparation for its return to Blaenau Festiniog as there were no turning facilities here.

The site is close to a nearby dam; part of the access road for this uses the formation of the Bala Ffestiniog line, passing close to the remains of a short bridge that carried the line into Bala Junction itself.
