Quintus is a Latin praenomen, or personal name, which was common throughout all periods of Roman history. It was used by both patrician and plebeian families, and gave rise to the patronymic gentes Quinctia and Quinctilia. The feminine form is Quinta.
Throughout Roman history, Quintus was one of the most common praenomina. Although many families did not use the name at all, it was particularly favored by others. The name continued to be used after the collapse of Roman civil institutions in the fifth and sixth centuries, and has survived to the present day.
Quintus is the Latin word for fifth. It is generally believed that the name was originally given to a fifth child, a fifth son, or a fifth daughter. However, it has also been argued that Quintus and the other praenomina of this type could refer to the month of the year in which a child was born. It may be that such names were given for both reasons.
