Giovan Battista Pigna (1530-1575) was an Italian humanist, poet and historian from Ferrara.
A reformer of the University of Ferrara, Pigna was secretary to Alfonso II d'Este, Duke of Ferrara and court historian at Ferrara.Pigna's I romanzi (1554) argued that chivalric romances like those of Ariosto were a modern form of poetry equal to those considered by Aristotle's Poetics.
Torquato Tasso, who succeeded Pigna as court historian, attacked Pigna's defence of Ariostan poetry in his Discorsi dell'arte poetica.
