The Cohors II Lucensium [equitata] (2nd cohort from the Conventus Lucensis [partly mounted]) was a Roman auxiliary unit. It is attested by military diplomas and inscriptions.
The cohort was stationed in the provinces of Moesia, Pannonia, Moesia Inferior, and Thracia, in that order. It is listed on military diplomas for the years 78 to 180/192 AD.
The first evidence of the unit in the province of Moesia is based on a military diploma dated to the year 78. The diploma lists the cohort as part of the troops stationed in the province.
