Gaius Cilnius Proculus was a Roman senator active during the reign of Domitian. He was suffect consul for the nundinium September–December AD 87 with Lucius Neratius Priscus as his colleague.Paul Gallivan, "The Fasti for A. D. 70-96", Classical Quarterly, 31 (1981), pp. 190, 217 It is unknown how or if Proculus is related to the better-known Gaius Cilnius Maecenas. Proculus is known only through surviving inscriptions.
Proculus was the governor of Moesia Superior; the period of his administration has recently been dated as extending from the year 100 to 102.Werner Eck and Andreas Pangerl, "Moesia und seine Truppen, Neue Diplome für Moesia und Moesia superior", Chiron, 38 (2008) p. 332 During his administration of the province, Proculus showed sufficient bravery in combat to be awarded dona militaria, or military decorations, likely as part of the Dacian Wars.Valerie A. Maxfield, "The Dona Militaria of the Roman Army", (Durham theses, Durham University, 1972), pp. 12f (Last accessed 11 August 2017) A Gaius Cilnius Proculus is known to be governor of Dalmatia during the reign of Trajan, but Werner Eck considers that governor was more likely the suffect consul of the nundinium of March/April 100, and the son of this Proculus.Eck, "Jahres- und Provinzialfasten der senatorischen Statthalter von 69/70 bis 138/139", Chiron, 13 (1983), p. 194
