Legio VI Hispana ("Sixth (Hispanian) Legion") may have been a legion of the Imperial Roman army. Only a few records attesting a "VI Hispana" were known in 2015. Seyrig (1923) argued that this unit was created in AD 68 and disappeared before 197. Another theory is that VI Hispana was created after 197 and was destroyed in the turmoil of the Empire's Third Century Crisis. The scarcity and ambiguity of records of "VI Hispana" has led some scholars to doubt that this legion ever existed and that the inscriptions attesting it were erroneous references to the legions VII Gemina or IX Hispana. Sources The extant records attesting a "Legio VI Hispana" are as follows: AE (2003) 1014 and 7 other similar inscriptions from Corinth honouring Tiberius Claudius Dinippus, who is described as a military tribune of "VI Hispana" (also called "VI Hispanensis" in 3 of the inscriptions).

Date ca. AD 100 Inscriptiones Aquileiae I.310. From Aquileia in northeastern Italy. Votive altar. The text reads: "[Dedicated] to the invincible god Mithras. Lucius Septimius Cassianus, standard-bearer of the legion IIIIII Hispana, acting in the lustrum of chief centurion Publius Porcius Faustus, freely fulfilled his vow to the well-deserving [god]." Date: AD 244-8. Legion lists It appears certain that no "VI Hispana" existed during the reign of Septimius Severus (r. 193–211). Two lists of the legions in being survive from this era, one inscribed on a column found in Rome () and the other a list of legions in existence "today" provided by the contemporary Greco-Roman historian Dio Cassius, writing ca. 210-232. Both these lists date from after 197, as both include the 3 Parthica legions founded by Severus in that year. Both lists provide an identical list of 33 legions. Therefore, if a VI Hispana ever did exist, it must have been either before or after Severus' reign. Theories Mistaken identity Theodor Mommsen, the 19th century German classicist, argued that the "IIIIII Hispana" of the Cassianus inscription was a misspelling of IX Hispana. This legion was sometimes written "VIIII Hispana". The mason may have mistakenly engraved "II" instead of "V". But there was (in 2015) no other evidence of the existence of IX Hispana later than 120.
