Before the Conquest of Wales was completed in 1282, Wales consisted of a number of independent kingdoms, the most important being Gwynedd, Powys, Deheubarth (originally Ceredigion, Seisyllwg and Dyfed), Gwent and Morgannwg. Boundary changes and the equal division of patrimony meant that few princes ever came close to ruling the whole of Wales.

The names of those known to have ruled over one or more of the kingdoms are listed below.
