Antipater of Sidon was a Greek epigrammatist from Phoenicia, active around 130 BCE. He was a friend of the philosopher Carneades and associated with the Stoic Panaetius of Rhodes. Renowned for his ability to compose extemporaneously, he traveled widely and participated in the literary circle of the Roman consul Gaius Lutatius Catulus. He died shortly before the time of Cicero.

His poetry is preserved exclusively in the Greek Anthology, which attributes over 70 epigrams to him. These works encompass dedications, erotic verses, ecphrastic descriptions, and epitaphs. His most famous epitaphs lament cities destroyed during the Mithridatic Wars and the Roman conquest, including a well-known poem for Corinth.

Antipater exemplifies the technical skill and learned allusiveness of the Hellenistic epigram. His verses provide a poignant literary record of contemporary historical upheavals. Highly regarded in antiquity, he influenced later poets like his namesake Antipater of Thessalonica and was preserved through the anthology tradition.
