San Lino is a Renaissance-style, Roman Catholic church and former monastery in Volterra, region of Tuscany, Italy.

[1] Raffaelo Maffei, a native citizen who had been theologian for both Popes Julius II and Sixtus IV, endowed construction of the church and enlargement of the adjacent monastery (1517) at a cost of 80,000 scudi.

The presbytery of the church contains a memorial bust (1522) of Maffei by Silvio da Fiesole (Silvio Cosini) with flanking statues of the Archangel Raphael and Beato Gerardo on his tomb by Fra Giovanni Angelo Montorsoli and Stagio Stagi.

[2] The interior ceiling is decorated with framed lunettes frescoed with images and scenes, including twelve Stories of the Life of Christ (circa 1618) by Cosimo Daddi.

It is flanked by two paintings by Cosimo Daddi, depicting St John the Evangelist and Christ in the Garden.
