Lesbia was the literary pseudonym used by the Roman poet Gaius Valerius Catullus (c. 82–52 BC) to refer to his lover. Lesbia is traditionally identified with Clodia, the wife of Quintus Caecilius Metellus Celer and sister of Publius Clodius Pulcher; her conduct and motives are maligned in Cicero's extant speech Pro Caelio, delivered in 56 BC.
