Gaius Octavius (about 100 – 59 BC) was an ancestor to the Roman Emperors of the Julio-Claudian dynasty. He is the father of the Emperor Augustus, step-grandfather of the Emperor Tiberius, great-grandfather of the Emperor Claudius, great-great grandfather of the Emperor Caligula, and great-great-great grandfather of the Emperor Nero. Hailing from Velitrae, he descended from an old, wealthy equestrian branch of the gens Octavia. Despite being from a wealthy family, his family was plebeian, rather than patrician. As a novus homo ("new man"), he would not be of a senatorial family.
