Osgod Clapa (died 1054), also Osgot, was a nobleman in Anglo-Saxon England during the reigns of Kings Cnut the Great, Harold Harefoot, Harthacnut, and Edward the Confessor.
Osgod is found as a witness to charters from 1026 onwards, but he first appears in narrative accounts on the occasion of the marriage of his daughter Gytha to his fellow-staller Tovi the Proud.
Edward the Confessor kept Osgod in his position of trust, and the reasons for his eventual outlawing in late 1046 are far from clear.
Gunnhild was first married to Håkon Eiriksson, son of Cnut's trusted ally Eiríkr Hákonarson, and later to Earl Harald, son of Thorkell the Tall, a trusted servant of King Harthacnut, which placed her in a prominent position among opponents of Edward the Confessor's kingship.
But there came upon them a strong wind, so that they were all lost but four persons, who were afterwards slain beyond sea.The Chronicle reports Osgod's death in 1054, "suddenly in his bed, as he lay at rest", apparently still in exile.
