Aalto Library is a part of the Aalto Centre in Seinäjoki and one of the 11 libraries Alvar Aalto designed. Aalto Library was completed in 1965 and until 2012 it served as the main library in Seinäjoki. The library was refurbished and restored back to the original design and reopened in 2015. Aalto Library and the Apila Library are connected with an underground passageway.

Aalto library also houses the Aalto information desk and the Aalto design glass collection, both owned and maintained by the City of Seinäjoki. The glass collection displays pieces designed by Aino and Alvar Aalto.
