Tongwynlais is a village and community in the north of Cardiff, Wales, north of the M4 motorway in the Taff Valley. It is notable as the location of the hillside landmark, Castell Coch. The population as of the 2011 census was 1871. 
Tongwynlais is believed[who?] to have obtained its name from the word ton (plural tonnau) meaning ley land, i.e. pasture, grassland or unploughed land, and Gwynlais, the name of a local family, thus "pasture of Gwynlais". (See also Tonna.)
Tongwynlais is located near Junction 32 of the M4 motorway, east of Bridgend and west of Newport and the A470 trunk road. It is situated 5 miles (8 km) north of Cardiff city centre and 7 miles (11 km) south of Pontypridd. The surrounding towns and villages are Pentyrch and Radyr to the west, Taffs Well and Caerphilly to the north, and Rhiwbina and Whitchurch to the south. Tongwynlais became part of Cardiff In 1974 when Cardiff expanded northwestwards.
Many consider Tongwynlais as the entrance to the South Wales Valleys from Cardiff, with its famous landmark, Castell Coch, on a hillside. The main route to the Valleys, and beyond to Mid Wales, the A470, runs alongside the village. To the north of the village is Fforest Fawr, a forest of about 100 hectares (250 acres) run by the Natural Resources Wales. Tongwynlais is separated from the rest of Cardiff by the M4 and the A470 to the south and west and hills and forestry to the east. Tongwynlais is considered to be part of the Cardiff North Rural Area.
The Cardiff Railway once ran through Tongwynlais. It passed through a tunnel just beneath Castell Coch. Tongwynlais railway station opened in 1911 and closed in 1931. The nearest station on the Coryton Line is Coryton railway station. Radyr railway station is also nearby.

It was built on top of the ruins of a 13th century castle thought to belong to Ifor Bach, a local Welsh ruler. It was rebuilt and transformed in the late 1870s into a fantasy castle by William Burges for the 3rd Marquess of Bute.
