St Patrick's, Carlow College, is a liberal arts college located in Carlow, Ireland. The college is the second oldest third level institution in Ireland and was founded in 1782 by James Keefe, then Roman Catholic Bishop of Kildare and Leighlin, and his co-adjutor bishop Daniel Delany.

Bishop Keefe initially attempted to open a seminary in Tullow, but instead took out a 999-year lease on the present site. During the nineteenth century, students studied Philosophy, Theology, Mathematics, Languages and Law at Carlow College. It was founded in 1782. The delay in accepting students was due to resistance from the local Church of Ireland Bishop, but the passing of the Roman Catholic Relief Act 1793 obviated the need for his permission.

From 1793 to 1892, it educated both lay people and those studying for the priesthood. In 1832, college president Father Andrew Fitzgerald O.P, was imprisoned as part of the Tithe War for his refusal to pay tithes.

In 1840, Carlow College was accredited by the University of London and over the succeeding decades students of the college sat the examinations for primary degrees in Arts (B.A.) and Law (LL.B.) from London.

In May 1847, Carlow College president Dr. James Taylor purchased a house and farm of 127 acres at Knockbeg and St. Mary's was opened there as a preparatory school to Carlow College, in 1892 lay students were transferred to Knockbeg. In 1866 Queen's University of Ireland engaged in a dialogue about empowering it to examine and confer degrees on students other than those of the Queen's colleges, the St. Patricks College Carlow Report was conducted and the college was deemed to meet the criteria, as evidenced by the courses examined and conferred by University of London, (the report listed all the students and professors at the time) however it was never enacted. This dialogue with the President James Walshe and the Queen's senate caused a dispute between Walshe and Cardinal Cullen. Ordained students and staff at the college produced The Carlow College Magazine.

In 1844, the Foreign Missions Fund was established after a bequest from Rev Maurice Kearney, and sometimes called the Kearney Fund, this allowed Bishops to Foreign Missions adopt and students to avail of bursaries to help them.

Following the University Education (Ireland) Act 1879 all Catholic colleges, including Carlow College, came under a reconstituted Catholic University of Ireland, and affiliated to the new Royal University of Ireland. Hence students could be matriculated and examined by the Royal University.

The National Centre for Liturgy moved to Carlow in 1978 where it was based until it moved to Maynooth in August 1996.

From 1892 to 1989, the college was operating principally as a seminary for the priesthood. Between 1793 and 1993 it is estimated that 3132 priests were ordained in Carlow. 1989 saw the college become affiliated to N.C.E.A. the forerunner of HETAC.

In 1993, a stone cross by the German artist Paul Schneider, was placed in the grounds to celebrate its bi-centenary, also a lecture was given by former college president Bishop Ryan.

In 1995, full-time degree students became entitled to the Irish Government's free fees scheme and local authority grants.

Distinguished among the thousands of its past students was one of the first-ever Catholic bishops to be appointed in the United States, John England; John Therry, Irish-Australian priest; Ireland's first cardinal, Paul Cullen; the artist Frank O'Meara; the Young Irelander and land-reform theorist, James Fintan Lalor, and Fenian John O'Leary. Daniel O'Connell, Ireland's predominant political leader in the first half of the nineteenth century, reputedly gave an oration to the Carlow townspeople from the top of the college's front porch. Descendants of O'Connell have studied and taught the college. Also educated in Carlow College were James Fintan Lalor's brothers, Richard Lalor, Irish Nationalist MP for Queens County, and Sir Peter Lalor, MP and Speaker of the Victoria Parliament, Australia.

Rev William Clancy (1802–1847), missionary and bishop in the United States and British Guiana, studied at Carlow.

The Jesuit and first president of UCD, Rev William Delany, received his early education at Carlow.

Some of the 17 students who had been expelled from Maynooth due to their support for the 1798 rebellion had attended Carlow, including Francis Hearn, who was later executed.

The Rt Rev Michael Collins, Bishop of Cloyne, who was expelled from Maynooth due to his support for Robert Emmet's rebellion, completed his studies at Carlow.

The Rev Daniel William Cahill, an editor of the Dublin Telegraph, attended Carlow College; he returned in 1825, as Professor of Natural Philosophy in Carlow College, a post he held until 1834. Amongst his pupils were the aforementioned Lalor brothers. Dr Cahill's nephew, Patrick Cahill, was also educated at Carlow College, obtaining an LLB from the University of London. He was a supporter of Irish Nationalism and Home Rule and later went on to found the Leinster Leader newspaper.

The nationalist Maurice Leyne and the physician and poet Richard D'Alton Williams (1822–1862) attended Carlow College. Poet and teacher William A. Byrne, (William Dara) also attended Carlow.

Patrick Moriarty OSA was the second president of Villanova College, and instrumental in its setting up, studied at Carlow, before joining the Augustinians.

Patrick Barry, Bishop of St. Augustine, Florida and co-founder of Barry University began his studies for the priesthood at Carlow College in 1890.

British General Sir Thomas Kelly-Kenny GCB GCVO (1840–1914) was also educated as a lay student at Carlow College.

Rev Thomas Nangle (1889–1972) from Canada, padre of the Royal Newfoundland Regiment in the first world war, studied for the priesthood at Carlow, later a Rhodesian farmer and MP.

The new facility incorporated the Delany Archive containing the archives of the Brigidine Sisters, the Patrician Brothers as well as the college and diocese. It effectively charts 200 years of education in the local area. The P.J.
