Macer Pompeius the Tragedian was a Hellenistic author of the 1st century BCE. His name suggests a possible connection to the Roman gens Pompeia, but no biographical details concerning his geography, background, or associations are preserved.

No specific works by Macer Pompeius survive, nor are they detailed in extant sources. He is identified as a writer of tragedy who composed in verse using the Koine dialect, but the title and subject of his single attributed work are unknown. His historical and literary significance remains indeterminate due to the complete absence of testimonia or fragments.
