Titus Eppius Latinus (fl. during the reign of Trajan) was the first known Pannonian Roman member of the ordo equester.

Latinus was born in Neviodunum (officially municipium Flavium Latobicorum, modern-day Drnovo) in the province of Pannonia. He was in the Quirina tribe and his father was called Titus.^[1] There are multiple theories on his ethnic origin. He may have come from a Northern Italic family moving from Aquileia^[1][2]—or a Dalmatian.^[1] Inscriptions set up by southern Gauls in the vicinity of his birthplace suggest that his ancestors lived in Southern Gaul.^[3] Another possibility is that—like the majority of provincial equites—he was a member of the local aristocracy that gained citizenship.^[1]

His nomen gentilicum could've been the Latinized version of the native Pannonian Epo or Eppo name present around Emona (modern-day Ljubljana) and Neviodunum,^[4] however, Eppius was very rare in Pannonia. It was also rare but present in Northern Italy,^[4][5] including Aquileia,^[5] and much more common in Southern Gaul.^[4][5] In Noricum it appears as Eppaeus.^[4] On the other, his cognomen was widespread in Northern Italy and Noricum.^[5] It asserts that he was of Roman origin but that may suggest he actually wasn't.^[1]

Unlike most equites, Latinus didn't start as a military officer.^[1] Before getting admitted into the ordo equester, he was duumvir of Neviodunum.^[1][6] Afterwards, he occupied multiple procurator posts under Trajan.^[1] He was procurator ad census accipiendos of a province with the job of carrying out a census, then procurator familiarum gladiatoriarum provinciarum Hispaniarum trium charged with administrating the companies that recruit gladiators from Hispania.^[1][6] Added up, these positions paid him 60,000 sestertii yearly.^[6] Later, Latinus worked as procurator IIII publicorum Africae overseeing the finances of Africa.^[1][6]
