The Library of Trinity College Dublin (Irish: Leabharlann Choláiste na Tríonóide) serves Trinity College, and is the largest library in Ireland. It is a legal deposit or "copyright library", which means that publishers in Ireland must deposit a copy of all their publications there without charge.^[2] It is the only Irish library to also hold such rights for works published in the United Kingdom.^[2] It is one of the most iconic and prominent landmarks of the university, and has housed the Book of Kells since 1661.

The Library is also the permanent home to the Brian Boru harp, a national symbol of Ireland, as well as a copy of the 1916 Proclamation of the Irish Republic. One of the four volumes of the Book of Kells is on public display at any given time.^[3] The volumes and pages shown are regularly changed; a new display case installed in 2020 facilitated all pages to be displayed, including many which had not been seen in public for several decades.^[4] Members of the University of Dublin also have access to the libraries of Tallaght University Hospital and the Irish School of Ecumenics, Milltown.
