Marcus Peducaeus Stloga Priscinus was a Roman senator active during the middle of the second century AD. He was ordinary consul for 141 as the colleague of Titus Hoenius Severus.^[1] An inscription from the Great Theatre at Ephesus mentions a Marcus Peducaeus Priscinus as proconsular governor of Asia in 155/156, whom professor Géza Alföldy, amongst others, has identified as this Priscinus.^[2] Priscinus is known only through surviving inscriptions.

Priscinus came of a Republican family, the Peducaei.^[3] His father was Marcus Peducaeus Priscinus, ordinary consul in 110.^[4] It has often been suggested that Priscinus adopted Marcus Peducaeus Plautius Quintillus, ordinary consul in 177; Quintillus was the birth son of Plautius Quintillus, consul in 159.^[5] The details of Priscinus' senatorial career have not yet been recovered.
