The battle off Carteia was a minor naval battle during the latter stages of Caesar's Civil War won by the Caesarians led by Caesar's legate Gaius Didius against the Pompeians led by Publius Attius Varus. Varus would then join up with the rest of the Pompeians at Munda to meet Caesar. Despite fierce resistance the Pompeians were defeated by Caesar and both Labienus and Varus were killed.
