Pedro de Lagarto (born circa 1465; died 1543 in Toledo) was a Spanish singer and composer of the Renaissance period.
In June 1490 he became master of the choirboys (claustrero), replacing Juan de Triana in the post.
By 1537, being deaf and blind, he asked to be relieved of his duties as chaplain; he died towards the end of 1543.
Four works have been explicitly attributed to him in the Cancionero Musical de Palacio: (: The villancicos draw on different themes: Andad, pasiones, andad is a love song also included in the Cancionero de la Colombina and in the Cancionero de Segovia; Callen todas las galanas compares the women of Toledo and Seville; and D'aquel fraire flaco is an anticlerical satire.
The romance, Quéxome de ti, ventura, is a lament against the twists of Fortune.
