Patrick Duggan (10 November 1813 – 15 August 1896) was an Irish Roman Catholic clergyman who served as the Bishop of Clonfert from 1872 until his death.
Duggan was born in Cummer, County Galway in 1813. He matriculated in Maynooth College in 1833 and he was ordained to the priesthood in 1841 and appointed curate to the parish of Kilmoylan and Cummer in County Galway, and later parish priest.
Duggan supported the Tenant Right League and the Home Rule movement. In the 1872 Galway County by-election, Duggan organized support for Captain (later Lieutenant-Colonel) John Philip Nolan who was favourably disposed towards tenant rights.
Nolan was elected but lost his seat on the grounds of undue clerical influence, and Duggan was brought to trial with others before the Court of Common Pleas, but the case collapsed and he was acquitted.
In 1884 he was requested by Michael Cusack and others to become patron of the planned Gaelic Athletic Association. Duggan declined due to illness, and suggested Thomas Croke, Archbishop of Cashel and Emly, in his place.
