Paolo Bellasio (20 May 1554 – 10 July 1594) was an Italian composer and organist of the late Renaissance.
He is generally considered to be a member of the Roman School, though unusually for the group he seems to have written only madrigals.
He was born in Verona, lived in Rome in 1582 in the service of Cardinal Filippo Boncompagni, and then in the next year traveled throughout Calabria, probably looking for a job as an organist.
According to his epitaph, Pope Clement VIII granted him the title Knight of the Golden Spur.
In addition he wrote a book of villanelle which included a part for lute, as well as a group of canzonettas.
