Gnaeus Pompeius Strabo (died 87 BC), often referred to as Strabo or Pompey Strabo in English, was a Roman from the rural province of Picenum . He became the first of his branch of the Pompeii to achieve senatorial status in Rome, despite the anti-rural prejudice of the Roman Senate. After proving his military talent, Strabo climbed the cursus honorum and became consul in the year 89 BC, in the midst of the Social War.

Strabo commanded Roman forces against the Italian Allies in the northern part of Italy. His three Roman legions were instrumental in Rome's victory. After his consulship and the war, Strabo retired to Picenum with all of his veteran soldiers. He remained there until 87 BC, when he responded to Lucius Cornelius Sulla's request for help against Gaius Marius. Strabo besieged Rome, but died before a battle was fought. Strabo's son, the famous Pompey the Great, took the legions back to Picenum once again.
