Gaspare Guercio (1611 - 1670/1679) was an Italian artist, nicknamed 'Guercio' and a major proponent of the Sicilian Baroque. He was principally a sculptor but also a designer of decorative schemes for architectural projects. He collaborated with his pupil Gaspare Serpotta, father of the more famous Giacomo Serpotta.
Born in Palermo, he was trained in sculpture by his father, a reputed 'marmoraio' and sculptor in his own right.
