Ysgol Gyfun Gymraeg Bryn Tawe is a Welsh-language comprehensive school based in Penlan, Swansea, southwest Wales.
It opened in 2003 to complement Ysgol Gyfun Gwyr and to provide additional capacity following the increased demand for Welsh-medium education in the area.
As a result, the school only reached its full complement of years 7-11 (ages 11–16) with its fifth intake of September 2007.
The site was previously occupied by Penlan Senior Comprehensive school for boys which had been attended by Welsh international rugby union players.
In September 2008, the new sixth form partnership was opened with Ysgol Gyfun Gŵyr and pupils have access to subjects on both sites.
