The Anonymous Historian is a conventional modern label for unnamed authors of historical works from Late Antiquity. The assigned dating of the 3rd to 6th centuries CE fits the period of many anonymous chronicles, epitomes, and ecclesiastical histories produced in the later Roman and early Byzantine world. No specific biographical details for this figure are recoverable.

While the source metadata notes three works, no specific titles for a single anonymous historian of this description are attested. Known anonymous works from this era, such as the Excerpta Latina Barbari or the Chronicon Paschale, are typically singular compositions or epitomes rather than a confirmed corpus of three texts from one author.

Such anonymous works are crucial for transmitting historical data, often preserving fragments of lost sources and reflecting the chronological or theological priorities of their time. They served practical functions in education and administration, with their scholarly value lying in their preserved content rather than literary originality.
