Saebert (died c. 616) was a King of Essex (c. 604 - c. 616). He was the son of Sledda. A tomb, found in Prittlewell in the autumn of 2003, is thought to be the burial chamber of Saebert. Several foil crosses, perhaps sewn into his shroud, correlate with the accepted history that Saebert was a convert to Christianity. Other funereal goods, such as glass and copper alloy bowls, indicate a continuation of pagan beliefs.
