Procopius of Gaza (c. 465-528 AD) was a Christian sophist and rhetorician, one of the most important representatives of the famous school of his native place. Here he spent nearly the whole of his life teaching and writing, and took no part in the theological movements of his time.

The little that is known of him is to be found in his letters and the encomium by his pupil and successor Choricius. He was the author of numerous rhetorical and theological works. Of the former, his panegyric on the emperor Anastasius alone is extant; the description of the Hagia Sophia and the monody on its partial destruction by an earthquake are spurious.

His letters (162 in number), addressed to persons of rank, friends, and literary opponents, throw valuable light upon the condition of the sophistical rhetoric of the period and the character of the writer. The fragment of a polemical treatise against the Neoplatonist Proclus is now assigned to Nicolaus, archbishop of Methone in Peloponnesus (ft. 12th century).

Procopius's theological writings consist of commentaries on the Octateuch, the books of Kings and Chronicles, Isaiah, the Proverbs, the Song of Songs and Ecclesiastes. They are amongst the earliest examples of the "catenic" (catena, chain) form of commentary, consisting of a series of extracts from the fathers, arranged, with independent additions, to elucidate the portions of Scripture concerned. Photius (cod. 206), while blaming the diffuseness of these commentaries, praises the writer's learning and style, which, however, he considers too ornate for the purpose.
