Pedro Guerrero (born c. 1520) was a Spanish composer of the Renaissance.
He was singer of the powerful dukes of Medina Sidonia from 1533 to 1536.
[1] He was the older brother of Francisco Guerrero and taught him music prior to Francisco's time studying with Cristóbal de Morales.
By 1560 he had taken a position as a singer in Santa Maria Maggiore in Rome.
Several sacred motets are extant, as well as about ten secular songs in Spanish, though these only survive in intabulated versions for vihuela.
