George Dowdall (1487 – 15 August 1558) was a sixteenth-century Irish cleric, who was twice Archbishop of Armagh. He was born in Drogheda, the son of Edward Dowdall. The Dowdall family came to Ireland from Dovedale in Derbyshire in the thirteenth century and settled in County Louth. Several members of the family became distinguished lawyers and judges. George had at least one brother, Christopher, who married Thomasine Cusack, a member of the prominent Cusack family of Cussington, County Meath. Christopher was the father of James Dowdall, who became Lord Chief Justice of Ireland.
