Bryn Celynnog Comprehensive School is an 11–18 mixed, English-medium, community secondary school and sixth form in Beddau, Rhondda Cynon Taf, Wales.

One of a series of schools with similarities in style by the Glamorgan County Architect, D Pugh Jones.

Shown on an Ordnance Survey map of 1948 with the same E-shaped plan as today.

A dotted line is shown across the rear, perhaps representing a fence which would have bounded a courtyard.
