Patrick Barrett (died 10 November 1415) was an Irishman who held religious and secular high offices in Ireland.
Patrick Barrett was an Augustinian Canon at Kells Priory in the Roman Catholic Diocese of Ossory, County Kilkenny.
After returning to Ireland, Barrett was restored to possession of the temporalities on 11 April 1401.
Despite complaints, common throughout the Middle Ages in Ireland, about "the dangers of the roads" he was able to go on assize in Munster and South Leinster in 1410 to hear "certain urgent causes".
[3] He was succeeded as Bishop of Ferns by Robert Whittey, who held the See for forty years and lived to be almost ninety.
