The Grande Bibliothèque (French pronunciation: [ɡʁɑ̃d biblijɔtɛk]) is a public library in Downtown Montreal, Quebec, Canada.

Its collection is part of Bibliothèque et Archives nationales du Québec (BAnQ), Quebec's national library.

[4] This is supplemented by the Saint-Sulpice collection of some 78,000 works, some dating back to the 1760s and including books from the personal libraries of such figures as Louis-Joseph Papineau and Louis-Hippolyte Lafontaine.

[6] The library's adapted book service holds more than 50,000 documents for the visually impaired, including Braille and audiobooks.

The Grande Bibliothèque, which had been a pet project of former Québec premier Lucien Bouchard, was designed by Patkau Architects from Vancouver and Croft-Pelletier/Gilles Guité from Quebec City.

These multi-storey areas are demarcated by walls of wooden slats, either allowing indirect natural light or blocking it according to the conservation needs of the collection.

In accordance with the Québec government's policy on integrating art and architecture, the building contains several integrated works of art: The Grande Bibliothèque is located at 475 De Maisonneuve Boulevard East (45°30′56.00″N 73°33′45.00″W / 45.5155556°N 73.5625000°W / 45.5155556; -73.5625000) at the corner of Berri Street, in the Quartier Latin adjacent to the Université du Québec à Montréal campus, in the borough of Ville-Marie.
