The Most Reverend George Joseph Plunket Browne (1795–1858) was an Irish Roman Catholic clergyman. Born to a "well-known Roscommon family", he served as Bishop of Galway from 1831 until 1844, and afterward as Bishop of Elphin, until his death on 1 December 1858. He was charged with being a "Cullenite" in 1855, that is, a follower of ultamontane Paul Cardinal Cullen.
Browne was born in 1795 in Dangan House in the parish of Kilmore, diocese of Elphin, near Carrick-on-Shannon. His ancestors came originally from Coolarne, Athenry, Co. Galway. The family residence was at Cloonfad, Co. Roscommon. At 17 years of age, in 1812, he entered Maynooth College, and was ordained in 1818. He was appointed Administrator of St. Peters Parish, Athlone from 1823 – 1825, and again in 1826 – 1831. In 1829 he lived at King Street, now Pearse Street, in Athlone. At the age of 36 he was chosen to fill the new see of Galway. On 31 July 1831 the Pope approved his appointment. Dr. Browne was consecrated in Athlone on October 23 that year. The ceremony was performed by Archbishop Oliver Kelly of Tuam, and assisted by Bishops Burke of Elphin, and McNicholas of Achonry. His motto was "Fortiter et Fideliter (Firmly and Faithfully). He carried out his administration in a peaceful and diplomatic manner. The great Daniel O'Connell justly called him "The Dove of Galway".
Browne was an enthusiastic learner of the Irish language, but found it difficult to master and by 1844 he proposed in a public letter that to facilitate this learning, it should be written phonetically. He encouraged secondary education and with Dr Ffrench he was joint patron of the new Patrican Brothers boys boarding school which opened in 1837 at Clarinbridge. He brought the Ursuline Order of nuns to Dangan on the Oughterard road beside his own residence in May 1839. He recognised the need to increase the number of church buildings and in May 1837 he left for England to collect money for the new St. Patrick's Church in Galway. He dedicated a new church in Oughterard in August of the same year. He had the disadvantage of being both popular & poor and was unable to make his ad limina visit to Rome in 1836 but instead sent a detailed written report. He estimated that his income was about one seventh of that of the average Irish Bishop of the time.
