Baron Upper Ossory was a title in the Peerage of Ireland. It was created on 11 June 1541 for Barnaby Fitzpatrick. This was in pursuance of the Surrender and regrant policy of King Henry VIII. Under the policy, Gaelic chiefs were actively encouraged to surrender their lands to the king and then have them regranted (returned) under a royal charter if they swore loyalty to him. Those who surrendered were also expected to speak English, wear English-style dress, remain loyal to the Crown, pay a rent and follow English laws and customs, abjure the Roman Catholic Church, and convert to Henry's new Anglican Church.
