The Callimachus Scholia are a body of ancient commentaries on the poetry of the Hellenistic poet Callimachus. Compiled by grammarians over several centuries, with significant work from the Roman Imperial through Late Antique periods, these annotations originate from the tradition of Alexandrian scholarship. The identities of the commentators are largely unknown, but their work is preserved in medieval manuscripts of Callimachus's poetry.

These scholia are not independent works but prose annotations found within manuscripts. Major collections include commentaries on the fragmentary Aetia, the relatively more complete Hymns, the Epigrams, and fragmentary works like the Hecale. All have been subject to abbreviation and textual corruption through centuries of manuscript transmission.

The scholia are critically important for the study of Hellenistic poetry and ancient scholarship. They preserve otherwise lost explanations of obscure myths, rare words, historical references, and textual variants, serving as an indispensable tool for reconstructing Callimachus's fragmentary texts. They also provide a direct view into the methods of ancient grammarians and the interpretation of sophisticated literary works in antiquity.
