Sæbbi of Essex was a 7th-century king who ruled the East Saxons. He initially shared power with his cousin Sighere starting in 664, but he later became the sole monarch of the kingdom. Unlike his cousin, who returned to paganism, Sæbbi remained a devout Christian throughout his reign. After thirty years of rule, he abdicated his throne to live a monastic life. He died in 695 and is recognized as a saint in both the Roman Catholic and Orthodox traditions.
