William Reeves (16 March 1815 – 12 January 1892) was an Irish antiquarian and the Church of Ireland Bishop of Down, Connor and Dromore from 1886 until his death. He was the last private keeper of the Book of Armagh and at the time of his death was President of the Royal Irish Academy.

Early life Born at Charleville, County Cork, on 16 March 1815, Reeves was the eldest child of Boles D'Arcy Reeves, an attorney, whose wife Mary was a daughter of Captain Jonathan Bruce Roberts, land agent to the 8th Earl of Cork. This grandfather had fought at the Battle of Bunker's Hill, and Reeves was born at his house in Charleville.

From 1823, Reeves was educated at the school of John Browne in Leeson Street, Dublin, and after that at a school kept by Edward Geoghegan. In October 1830, he entered Trinity College Dublin, where he quickly gained a prize for Hebrew and was elected a Scholar in classics in 1833. In his third year, he became a scholar and went on to graduate BA in 1835. He proceeded to read medicine, won the Berkeley Medal, and graduated MB in 1837. His object in taking his second degree was that he intended to become a clergyman and to practice the medical profession among the poor of his parish.(Rev.) William Reeves biography at Ricorso

Life and work In 1838, he was appointed Master of the diocesan school in Ballymena, County Antrim, and was ordained a deacon of Hillsborough. The next year, he was ordained a priest of the Church of Ireland at Derry.Cleeve, Brian, & Anne Brady, A Dictionary of Irish Writers (Dublin: Lilliput, 1985)

In 1844, Reeves rediscovered the lost site of Nendrum Monastery when he visited Mahee Island in Strangford Lough, County Down, searching for churches recorded in 1306, and recognised the remains of a round tower.Macdonald, Philip, Monitoring at Nendrum, Mahee Island, Co.

By 1845, Reeves was corresponding with the Irish scholar John O'Donovan, and an archive of their letters between 1845 and 1860 is preserved at University College, Dublin. In July 1845, Reeves visited London.Hastings, Angela, University College Dublin Library Special Collections John O'Donovan/William Reeves correspondence, undated, at ucd.ie (pdf file)

Reeves's career was furthered by his learned work. His first book, published in 1847, was his Ecclesiastical Antiquities of Down, Connor and Dromore, but by then he was already a member of the Royal Irish Academy.Reeves, William, Ecclesiastical Antiquities of Down, Connor and Dromore, consisting of a Taxation of those Dioceses (1847) title page online at books.google.com By the time he published his Acts of Archbishop Colton (1850) he was also a Doctor of divinity. In 1850, as in 1847, he was Perpetual Curate of Kilconriola.

Reeves resided in Ballymena from 1841 to 1858, when he was appointed vicar of Lusk following the success of his edition of Adomnán's Life of Saint Columba (1857), for which the Royal Irish Academy had awarded him their Cunningham Medal in 1858. He had worked on this with Dr James Henthorn Todd, who was patron of the living at Lusk. Reeves's edition of Adomnán's Life of Columba has been called "the best and fullest collection of materials on the early Irish Church in one volume". With regard to the Celtic Church, Reeves himself described Adomnán's work as –

In 1853, Reeves bought from the Brownlow family the important 9th-century manuscript known as the Book of Armagh, paying three hundred pounds for it. He sold the book for the same sum to Archbishop Beresford, who had agreed to present it to Trinity, Reeves's alma mater.Book of Armagh in the Catholic Encyclopedia online at newadvent.org"In 1855, through the intervention of William Reeves, the Book of Armagh was presented to TCD": Gwynn, John, ed., Liber Armachanus (1913)

Reeves was a friend of Margaret Stokes and with his colleague Todd is credited with setting off her interest in Irish antiquities.

The author and antiquarian Samuel Ferguson wrote of Reeves in 1867:

In November 1889, Reeves had bought the important collection of Irish manuscripts of Robert Shipboy MacAdam (1808–1895), a Belfast business man and archaeologist. In 1892, after Reeves's death, this collection was bought for the Royal Irish Academy by Maxwell Close and is still held by the Academy, under the name of 'The Mac Adam and Reeves Collection'.The Catalogue of Irish Manuscripts in the Royal Irish Academy online at ria.ie (pdf file)
