Teigl Halt was a solely passenger railway station which served the rural area of Cwm Teigl, south of Blaenau Ffestiniog, Wales.

The Festiniog & Blaenau Railway (F&BR) was a narrow gauge railway built in 1868 to connect the town of Blaenau Ffestiniog in Wales with the slate quarries around Tanymanod and the village of Llan Ffestiniog, 3+1⁄2 miles (5.6 km) to the south. At Blaenau Ffestiniog it made a direct connection with the Festiniog Railway (FR) with which it was closely associated during its fifteen-year life. The railway was purchased by the Bala and Festiniog Railway in 1883 and converted to 4 ft 8+1⁄2 in standard gauge to extend the Bala Ffestiniog line, a branch of the GWR's line from Ruabon to Barmouth.
