William de Burgh, 3rd Earl of Ulster and 4th Baron of Connaught (17 September 1312 – 6 June 1333), was an aristocrat in the Peerage of Ireland.

  Death Notes:

In November 1332, at Greencastle, near the mouth of Lough Foyle, he had his cousin Sir Walter Liath de Burgh starved to death. In revenge, Sir Walter's sister, Gylle de Burgh, wife of Sir Richard de Mandeville, planned his assassination.

In June 1333, he was killed by de Mandeville, Sir John de Logan, and others. The Annals of the Four Masters noted that William Burke, Earl of Ulster, was killed by the English of Ulster. The Englishmen who committed this deed were put to death, in divers ways, by the people of the King of England; some were hanged, others killed, and others torn asunder, in revenge of his death.

William married Maud (Matilda) OF LANCASTER, daughter of Henry OF LANCASTER 3d Earl of Lancaster and Maud CHAWORTH, in 1327. (Maud (Matilda) OF LANCASTER was born circa 1310, died on 5 May 1377 and was buried in Bruisyard Abbey.)
