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 1,871.

==Toponymy== The name Tongwynlais is believed to be derived from the word meaning 'ley land', i.e. 'pasture, grassland or unploughed land'; and Gwynlais, the name of the stream that runs through the village, Nant Gwynlais, thus "pasture by the Gwynlais". Gwynlais means pure voice in Welsh. (See also Tonna.)
