Michael Northburgh, otherwise Michael de Northburgh (Northborough), was the Bishop of London between 1354 and his death in 1361. He was the nephew of Roger Northburgh, Bishop of Coventry and Lichfield. Northburgh's uncle's influence enabled him to be appointed Archdeacon of Chester in 1341 (until forced to resign in 1342) and Archdeacon of Suffolk in 1347 (until 1353) before he had been ordained into higher orders. Whilst archdeacon he became Rector of Pulham St. Mary (1341) and acquired many canonries. He occupied the office of Lord Privy Seal between 1350 and 1354.
