Giorgio Grognet de Vassé (1774–1862) was a Maltese architect and antiquarian, who is mostly known for designing the Mosta Basilica, popularly known as the Rotunda of Mosta. In the late 18th century, he studied at Frascati in the Papal States to become a priest. However, he developed a strong support for the Jacobins, and he joined the French expeditionary force as an officer during the Egyptian campaign. He eventually returned to Malta in the 19th century, some years after the uprising against French rule had ended.
