Giovan Battista Lalli (1 July 1572 – 6 February 1637) was an Italian poet and jurist.

[2] His mock-heroic poems, La moscheide ouero Domiziano il moschicida (1624), recounting the Emperor Domitian's war against the assembled armies of flies, and La franceide ouero del mal francese (1629) adapted Marinist conceptismo to the comic repertory.

His L'Eneide travestita (The Aeneid Disguised, 1633), a parody of the Aeneid of Virgil making fun of the feudal cult of heroes, was imitated in the Virgile travesti by Paul Scarron, which in turn inspired a whole series of adaptations both in Germanic and Slavic languages, from Charles Cotton's Scarronides to the Eneida by Ivan Kotliarevsky.

[3][4] Lalli attempted serious imitation of Torquato Tasso's Jerusalem Delivered and Giambattista Marino's Gerusalemme distrutta in his epic Tito Vespasiano ouero Gerusalemme desolata, a poem upon the siege of Jerusalem (1635).

[2] Later in his life Lalli retired to his native Norcia, where he died on February 6, 1637, at the age of 64.
