Ri'erha I (c. 835 – 18 August 909) was the son of Kederm I. He was King of Trellin and Emperor of Hysera from 858 to his death. He was succeeded by his second cousin, Stediz of Tidera.

Ri'erha was an unusually long-lived monarch, and his reign of 51 years saw him continue his father's reforms of Hyseran law codes and resume the kingdom's colonisation of the Rezati coast. Several contemporary writers refer to his courtiers as "waiting for [him] to die" from about 890 onward, as he failed to give them the war with Pelna for which they clamoured, nor did he make any suggestions as to who would succeed him - for Ri'erha was unmarried and childless. When he died without an heir in 909, there was a brief civil war wherein his second cousin, Stediz of Tidera, captured Mar'theqa, had himself crowned king Stediz IV and defeated several other claimants, founding House Tiderinë.
