A national library is a library established by a government as a country's preeminent repository of information. Unlike public libraries, these rarely allow citizens to borrow books. Often, they include numerous rare, valuable, or significant works. A national library is that library which has the duty of collecting and preserving the literature of the nation within and outside the country. Thus, national libraries are those libraries whose community is the nation at large. Examples include the British Library in London, and the Bibliothèque nationale de France in Paris.

The National Library of Colombia is a national library located in Bogota, Colombia. The library is a dependency of the Colombian Ministry of Culture.
