Alonso Lobo (February 25, 1555 (baptised) – April 5, 1617) was a Spanish composer of the late Renaissance.
In 1593, Toledo Cathedral hired him as maestro de capilla; he remained there until 1604, when he returned to Seville, where he died.
Lobo's music combines the smooth contrapuntal technique of Palestrina with the sombre intensity of Victoria.
Lobo was influential far beyond the borders of his native Spain: in Portugal, and as far away as Mexico, for the next hundred years or more he was considered to be one of the finest Spanish composers.
His works include masses and motets, three Passion settings, Lamentations, psalms and hymns, as well as a Miserere for 12 voices (which has since become lost).
