Kederm I (25 June 784 – 9 October 858) was the son of Tovelindra I. He was King of Trellin and Emperor of Hysera from 821 to his death. He was succeeded by his elder son, Ri'erha I.

With Trellin's ancient rival, Hysera, having fallen to his mother, and a treaty having been signed with its successor states, the kingdom under Kederm found itself in the unusual position of having no enemies to the north. Instead, he spent much of his early reign in Hyser, familiarising himself with the Hyseran law codes and instituting minor reform to bring them more in line with Trellin's. He did not pursue his military ambitions until the 840s, when he personally led an army into the County of Pelna and besieged the fortress of Rosnai, which for over a century had restricted Trellinese expansion along the Serëtanz. After seven months the garrison surrendered and remained firmly in Trellinese possession thereafter.
