Romeo Querini was a 13th-century Venetian nobleman and administrator.

Romeo Querini is first attested in 1209 in Venice.^[1] By May 1229 he was already serving as the Venetian Podestà of Constantinople. As his predecessor, Giovanni Querini, was still in office in December 1228, and assuming a normal tenure of two years, Romeo Querini likely remained in office until 1231.^[1]

Querini served as ducal councillor in Venice in 1233/34 and again in 1234/35, and as ambassador to Pope Gregory IX in 1239.^[1] He is finally attested as governor (podestà) of Chioggia in 1241.^[1]
