Azzolino Bernardino della Ciaja (21 May 1671 – 15 January 1755) was an Italian organist, harpsichordist, composer and organ builder.
Born in Siena, into a rich family, he was a member of the Pisan Cavalieri di S Stefano order.
He lived in Pisa from 1703 and 1713, but kept strong connections with Florence.
Very important are the Six Sonatas for Harpsichord published in Rome in 1727.
