Callinicus Rufinianus is an obscure figure of the Greco-Roman imperial period, as no biographical details are recorded in major reference works. His name combines the Greek "Callinicus" with the Latin cognomen "Rufinianus," suggesting a cultural context of the first to fourth centuries CE.

He is associated with a single biographical work, though its title and content are unattested. The author's historical significance remains undetermined due to the absence of surviving works or reliable testimonia.
