Cadell ap Brochfael ('Cadell, son of Brochfael'; died c. 808), also known as Cadell Powys, was an 8th- and 9th-century king of Powys.
He was the son of Brochfael ab Elisedd, whom he succeeded to the throne c. 773.
The Annals of Wales mention his death, and Phillimore's reconstruction dates the entry to AD 808.
[2][1] Some genealogies claim that his daughter Nest became the wife of Merfyn Frych, the king of the neighbouring kingdom of Gwynedd.
