Publius Cornelius Dolabella (fl. 1st century BC) was a Roman senator who was appointed suffect consul in 35 BC.
A member of the patrician Dolabella branch of the gens Cornelia, Dolabella was probably the son of Publius Cornelius Dolabella, who was Praetor in 69 BC and then proconsular governor of Asia in around 68 BC. Much of his career is unknown; it is postulated that he may have been a triumvir monetalis in Sicily at some point early in his career. Appointed consul suffectus in 35 BC to replace Sextus Pompeius, it is not known whether he was a partisan of Gaius Julius Caesar Octavianus or Marcus Antonius. He also perhaps may have been the Dolabella who accompanied Augustus to Gaul around 16 – 13 BC.
It is speculated that Dolabella married a Quinctilia, a sister of Publius Quinctilius Varus, and that their son was Publius Cornelius Dolabella, who was Roman consul in AD 10.
