Coláiste Rís, formerly Dundalk CBS, was established on 10 May 1869 by the Congregation of Christian Brothers which is an order of Brothers, not monks or priests, called to consecrated life. The first student was John Kelly from Dundalk. The Christian Brothers were invited to form a school by Archbishop Michael Kieran of Armagh because, in his own words, "they gave the best education that has been offered to the youth of Ireland".
The founder of the school was Brother Louis Yorke, an Englishman born in Manchester into a Protestant family. When he died, in June 1907, the town of Dundalk came to a standstill. The street where the school stands was renamed to Yorke Street in his honour, commending his great service to the education of young people in the area.
Within a year of the school opening there were 500 boys enrolled. This required some major extensions and the development of facilities has continued constantly in the years since then. A recent addition was a Technological Wing built with financial contribution from Senator Edward Haughey, a past pupil.
In 1922, when the Irish Free State was established, the school adopted the ideals of the new state. Students began to study their subjects through Irish in 1925 and in 1934 the school won Corn na Dála, the Dáil Cup, as the best in Ireland for the promotion of Irish culture.
One of the four streams offer subjects through the medium of Irish Gaelic up to Junior Certificate Level but then students have to study through the English language only.
Among other successes in recent years were Irish Senior Golf Champions in 1981, numerous national titles in Debating, 1916 Scholarships, Leinster Senior Football and Young Scientist of the Year.
In 1987, it was found that girls who had been educated through Irish at primary level had no option for secondary education through Irish in Dundalk, it was with this in mind that the first group of 11 girls were enrolled into the school. The first female to appear on the school registers was Aoife Hamill, in September of that year. In the subsequent years the number of female students has grown rapidly, today the ratio is about 2:1, males to females.
On 1 August 1990, the Christian Brothers left Dundalk after 121 years and handed over the school to the Armagh Diocese, with Cardinal Tomás Ó Fiaich as the chief trustee and patron. A new Board of Management had taken over management of the school in 1986 and that same year Mr Frank Cooney had been installed as the first lay-principal. The name was changed to Coláiste Rís, signifying no further association with the Christian Brothers. Before the Brothers left Dundalk they were honoured in the annual Saint Patrick's Day parade for their contribution to the town.
The new 2000 millennium has seen the school adapt itself to the rapid changes of multi-cultural Ireland. Though the ethos of the school is Christian, students of other religions are welcomed with respect and tolerance.
The school today is a Diocesan college under the trusteeship of the Archdiocese of Armagh, it continues its tradition of focused learning through Irish and English with a flair for Debating and Irish sports.
The school is made up from a mixture of modern buildings as well as the old monastery which is designated as a heritage site, the school grounds have now been fully developed to a point where there is no further space for new buildings. The school playing fields are a short walk away. In 2019 the school will celebrate its 150th anniversary and plans are already underway to mark the occasion.
In May 2010, Kevin Wynne announced he was to step down from his position as head teacher after 9 years. His successor has been named as Pádraig Hamill, who has been a Maths and Science teacher at the school for the last three decades.

Many of the school's activities for students and staff are outside normal operating hours, including debating, sports, and science.
Coláiste Rís is regarded as one of the strongest schools in the country for Irish Debating, the school debate team has reached the All-Ireland Irish Debating Championship the last eleven years in a row. Seán Ó Coigligh, an Irish teacher in Coláiste Rís, has played a key role in preparing the teams every year.
The school has long had an accomplished record in the sporting field, especially in Gaelic football and in hurling, as well as soccer.
In science, Colaiste Rís is second to none in County Louth for having a track record of winners at the annual Young Scientist Competition. The students have collected countless awards from the competition, including awards from the Irish Geological Society, the Irish Association of Speech Therapists, and many others. The most outstanding student in this regard is Thomas Gernon, who won prizes in the years 1997, 1998, 1999 and 2000. In 2000 he was the overall winner of the competition, and became Irish Young Scientist of the Year. Thomas then went to Amsterdam and collected another prize in the pan-European competition.
