John of Caesarea in Palestine (Ἰωάννης ὁ Καισαρείας τῆς Παλαιστίνης) was a Christian grammarian and rhetorician active in the 6th century CE. He worked within the late antique educational system, and his identification with Caesarea Maritima places him within a major center of Palestinian scholarship, a tradition that included figures like Procopius of Gaza [1]. No specific biographical details are recorded.

He is identified as the author of grammatical and rhetorical treatises, though the specific titles and contents of these works are not detailed in the available sources [1].

John represents the continuity of classical grammatical education within a Christian, late antique context. His work illustrates the maintenance and adaptation of the trivium by Christian scholars following the decline of pagan institutions. As a grammarian from Caesarea, a city with a renowned library and scholarly history, he contributes to understanding the transmission of linguistic knowledge in the Byzantine world prior to the Islamic conquests [1].
