Marcus Ulpius Leurus was a Roman senator, who was active during the reign of Septimius Severus and Caracalla.
He was suffect consul in some undetermined nundinium in their reigns.
Leurus had his origins in Thessaly, then part of the province of Macedonia;[2] his gentilicium suggests he is descended from a man who obtained Roman Citizenship in the time of Trajan.
Leurus is attested as having married Flavia Habroea; John H. Oliver has traced her paternal lineage, consisting of a number of prominent men of Hypata, for three generations.
[3] Together they had a son, Marcus Ulpius Eubiotus Leurus, also a suffect consul around the year 230.
