Lucius Scribonius Libo was a Roman politician and military commander who was consul in 34 BC and brother-in-law to the future emperor Augustus. Libo rose to prominence through his connections with Pompey. When Julius Caesar rebelled against the Roman Senate in 49 BC, Libo sided with Pompey. He carried out a variety of military, diplomatic and naval roles, with mixed success.
After Pompey's death in 48 BC, Libo attached himself to Pompey's son, Sextus Pompey, Libo's son-in-law due to his marriage to Libo's daughter Scribonia. Libo was involved in a variety of negotiations with Octavian. In 35 BC Libo abandoned Sextus and was rewarded by being appointed consul in 34 BC.
