Eanfrith (590–634) was briefly King of Bernicia from 633 to 634.
Eanfrith married a Pictish princess and had a son, Talorcan, who later became a king of the Picts (653–657). Edwin was killed by the army of Cadwallon ap Cadfan of Gwynedd and Penda of Mercia at the Battle of Hatfield Chase in October 633, If there was a friendly relationship between Eanfrith and Cadwallon at first, however, it must not have lasted, since Bede reports that Eanfrith went to Cadwallon "with only twelve chosen soldiers" in an attempt to negotiate peace, but Cadwallon had him killed.
