The Biblioteca or Library of San Domenico is in the convent of the Dominican Order, San Domenico in Bologna, region of Emilia Romagna, Italy.

A library was founded soon after the convent was built, linked to the School of Theology run by the convent. The library layout is a basilica structure with a series of columns and rounded arches, modelled in 1466 by Giovanni Rossi after the Library of San Marco of Florence. Other sources cite Gaspare Nadi, as the architect.^[1] Part of the library complex is now the seat of the faculty of philosophy and theology, run by the Dominicans.

At one end of the library is a room built in 1497 by the jurist Ludovico Bolognini. The room has Renaissance-style decoration with stuccoes by Antonio Maria Fontana. It has a painting of St Thomas Aquinas by Marcantonio Franceschini.^[2]

It contains a collection of 35 ancient choral books written on parchment.
