Cú Choigríche Ó Duibhgeannáin (fl. 1627–1636), also styled Peregrine Ó Duibhgeannáin or Peregrine O'Duignan, was an Irish historian and chronicler. Born Cú Coigriche mac Tuathal Ó Duibhgeannáin, about or after 1590, his name was Latinized to Pereginus (anglicized Peregrine) when he took holy orders in the Franciscan Order based at Leuven, now in Belgium. Cú Coigriche (also Cuchogry) means "hound [or hero] of the neighbouring [or foreign] land." His family, the Clan Uí Dhuibhgeannáin, were professional historians from Annaly, many of whom had crossed the Shannon and practised their art in Connacht. Here the Ó Duibhgeannains set up a bardic college at Kilronan, near Lough Key in northern County Roscommon.
