Marcus Arrecinus Clemens

Marcus Arrecinus Clemens (fl 1st century), was a Roman senator who served as prefect of the Praetorian Guard.

Arrecinus Clemens was born into an Equestrian family from Pisaurum, being the homonymous son of Emperor Gaius' Praetorian Prefect. Clemens' sister was Arrecina Tertulla, the first wife of the future Emperor Titus. Despite being a member of the Senate, he was placed at the head of the Praetorian Guard in 70 by Vespasian's political ally, Gaius Licinius Mucianus, amidst concerns that his predecessor Arrius Varus was growing too influential. He held the position until June of 71, when Vespasian's son Titus replaced him. According to Tacitus, Clemens was chosen because his father, Marcus Arrecinus Clemens, had honourably commanded the Guard during the reign of Emperor Gaius in 38.

In the sequel Clemens held a suffect consulship in 73, governed the province of Hispania Tarraconensis, held a second consulship in 85, and was made city prefect of Rome in 86. It is believed he died during the reign of Titus' brother Domitian.
