Henry O'Callaghan Prittie, 4th Baron Dunalley (21 March 1851 – 5 August 1927), was an Anglo-Irish peer.
He was educated at Harrow School and Trinity College, Cambridge.
[2] He succeeded his father as fourth Baron Dunalley in 1885 but as this was an Irish peerage it did not entitle him to an automatic seat in the House of Lords.
However, in 1891 he was elected an Irish representative peer, which he remained until his death.
He died in August 1927, aged 76, and was succeeded in the barony by his son Henry.
