The Irish College in Paris (Irish: Coláiste na nGael, French: Collège des Irlandais, Latin: Collegium Clericorum Hibernorum) was for three centuries a major Roman Catholic educational establishment for Irish students. It was founded in the late 16th century, and closed down by the French government in the early 20th century. From 1945 to 1997, the Polish seminary in Paris was housed in the building. It is now an Irish cultural centre, the Centre Culturel Irlandais.

The religious persecution under Elizabeth and James I led to the suppression of the monastic schools in Ireland in which the clergy for the most part received their education. It became necessary, therefore, to seek education abroad, and many colleges for the training of the secular clergy were founded on the continent, at Rome, in Spain and Portugal, in Belgium, and in France.

The founder of the Irish College in Paris was John Lee, an Irish priest who came to Paris, in 1578, with six companions, and entered the Collège de Montaigu. Having completed his studies he became attached to the Church of St. Severin, and made the acquaintance of a French nobleman, John de l'Escalopier, President of the Parlement of Paris, who placed at the disposal of the Irish students in Paris a house in the rue de Sèvres, which served them as a college. Lee became the first rector in about 1605.

Lee was followed by Thomas Dease, who was rector until 1621 when he was appointed Bishop of Meath. By letters patent dated 1623, Louis XIII conferred upon the Irish priests and scholars in Paris the right to receive and possess property. It was during the tenure of Dease's successor, Thomas Messingham, that the Irish college was recognised as a seminary by the University of Paris in 1624. Messingham organized the course of studies with a view of sending forth capable missionaries to work in their native country.

The college founded by Lee was not spacious enough to receive the numerous Irish students who came to Paris. Some of them continued to find a home in the Collège Montaigu, others in the Collège de Boncourt, while some, who were in affluent circumstances, resided in the Collège de Navarre. This situation attracted the attention of Vincent de Paul and others, who sought to provide them with a more suitable residence.

In 1672, the bishops of Ireland, deputed John O'Molony, Roman Catholic Bishop of Killaloe, to treat with Colbert as to the establishment of a new college. This was eventually obtained, through the influence of two Irish priests resident in Paris: Patrick Maginn, formerly first chaplain to Queen Catherine, wife of Charles II of England; and Malachy Kelly, one of the chaplains of Louis XIV. These two ecclesiastics obtained from Louis XIV authorisation to enter possession of the Collège des Lombards, a college of the University of Paris founded for Italian students in 1333. They rebuilt the college, then in ruins, at their own expense, and became its first superiors. The acquisition of the college was confirmed by letters patent dated 1677 and 1681. Some years later the buildings were extended by John Farely, and all the Irish ecclesiastical students in Paris found a home in the Collège des Lombards. ^{[citation needed]}

The Irish College in Paris was open to all the counties and provinces in Ireland. In 1738, the college chapel was rebuilt under the direction of the architect Pierre Boscry. The number of students went on increasing until, in 1764, it reached 160. It was therefore found necessary to build a second college. The building was commenced in 1769 in rue du Cheval Vert, now rue des Irlandais, and the junior section of the students was transferred to the new college in 1776. The students were divided into two categories, one, the more numerous, consisting of priests already ordained in Ireland, and the other of juniors aspiring to orders. Both sections attended the university classes, either at the Collège de Plessis, or at that of Navarre, or at the Sorbonne. The course of study extended over six years, of which two were given to philosophy, three to theology, and one to special preparation for pastoral work. The more talented students remained two years longer to qualify for degrees in theology, or in canon law. ^{[citation needed]}

In virtue of the papal bull of Pope Urban VIII, Piis Christi fidelium, dated 10 July 1626, and granted in favour of all Irish colleges already established or to be established in France, Spain, Flanders, or elsewhere, the junior students were promoted to orders ad titulum missionis in Hiberniâ, even extra tempora, and without dimissorial letters, on the representation of the rector of the college – a privilege withdrawn, as regards dimissorial letters, by Pope Gregory XVI. The students in priestly orders were able to support themselves to a large extent by their Mass stipends. Many burses, too, were founded for the education of students at the Lombard college. Among the founders were nine Irish bishops, thirty-two Irish priests, four medical doctors, some laymen engaged in civil or military pursuits, and a few pious women. The college was governed in the eighteenth century by four Irish priests called provisors, one from each province of Ireland. They were elected by the votes of the students and confirmed by the Archbishop of Paris, who, as superior major, nominated one of them to the office of the principal. In 1788, the system of government by provisors was abolished, and one rector was appointed.
