Lucius Cornelius Pastor Vincens (65 BCE - CE 25), better known to his contemporaries as Vincens, Cornelius Vincens or Pastor Vincens, was a Roman consul and general in the Late Republic and Early Empire.
He was born Lucius Octavius Pastor, from Octavii Pastores, a distant related family of the Octavii Rufi which the future emperor Caesar Augustus (then known as Gaius Octavius Rufus Thurinus) came from. His father with the same name was a municipal magistrate at their hometown Sicily in 70s BCE. His paternal grandfather was Titus Octavius Pastor, a minor figure in the reforms of his more famous fellow Sicilian resident, Titus Caecilius Metellus. His paternal ancestors include Lucius Octavius Pastor, a shepherd who lived in Sicily and gave the ancient Roman king Ancus Marcius his hiding place while the latter was followed by a group of bandits. His mother was Marca Caecilia Metella, a niece of Titus Caecilius Metellus, and her father was Gaius Caecilius Metellus, Titus' younger brother.
