Tynewydd is a village located in the County Borough of Rhondda Cynon Taf, south Wales.

It is believed that the village was named after 'Tynewydd' (built 1652) a longhouse in nearby Blaenrhondda.

In 1865 Ebenezer Lewis, the owner of the Bwllfa Dare Colliery in Aberdare, purchased the lease of mineral property at Tynewydd on the east side of the River Rhondda.

[1] In 1887 the mine was purchased by Messrs L and H Gueret, and efficient production was re-established.
