The Andorra National Library (Catalan: Biblioteca Nacional d'Andorra) was founded in 1930, then re-opened in 1974.

It was initially housed in the hall of lost steps (sala dels passos perduts) in the Casa de la Vall (the headquarters of the General Council of Andorra).

Its creation resulted from an initiative of the Andorran Society of Barcelona Residents (Sociedat Andorrana de Residents a Barcelona) together with contributions from various private individuals, and followed in the wake of the founding of other socio-cultural entities, such as the Association for the Protection of Catalan Education (Associació Protectora de l'Ensenyança Catalana).

[2] In 2020, the library was moved to the former Hotel Rosaleda in Encamp, a building of national cultural interest.

This allowed the institution to further increase space available for its growing collections, as well as offer a fully accessible facility to patrons.
