Edward Somerton, or Somertoun (died 1461) was an Irish barrister and judge who held the offices of Serjeant-at-law (Ireland) and judge of the Court of King's Bench (Ireland) and the Court of Common Pleas (Ireland). He was born in Ireland, possibly in Waterford. By 1426 he was a clerk in the Court of Chancery (Ireland), and was paid 26 shillings for his labours in preparing writs and enrolment of indentures. In 1427 he is recorded in London studying law at Lincoln's Inn. He returned to Ireland and was appointed King's Serjeant for life in 1437; he also acted as counsel for the city of Waterford, a position subsequently held by another future judge, John Gough.
