Egidio Querini was a 13th-century Venetian nobleman, ambassador, and administrator.
Egidio Querini is first mentioned as the Venetian Podestà of Constantinople, on 4 April 1247, and was likely in office at least since the previous autumn. The exact dates of his tenure are unknown, but must have been sometime between 1245 and 1248.[1]
After the end of his tenure, he served as ducal councillor in Venice in 1250, and ambassador to Pope Urban IV in 1261.[1] Probably due to his experience in Constantinople, he took part in the negotiations and ratification of the Byzantine–Venetian treaty of 1268.[1]
