Andriscus, also called Pseudo-Philip, was a pretender to the Macedonian throne in the mid-2nd century BCE. Claiming to be Philip, a son of the defeated King Perseus, he invaded Macedonia with Thracian support in 149 BCE. He defeated a Roman force and briefly ruled, but his cruel reign alienated his subjects.

He was defeated by the Roman consul Quintus Caecilius Metellus at the Second Battle of Pydna in 148 BCE. Captured and paraded in a Roman triumph in 146 BCE, his defeat led directly to Macedonia’s annexation as a Roman province.

No surviving written works by Andriscus are attested. The historical accounts of his life and rebellion come solely from later historians like Polybius and Livy.

Andriscus’s rebellion, known as the Fourth Macedonian War, was the final catalyst for Rome’s direct annexation of Macedonia, ending the region’s political instability. He is remembered as the last figure to claim the Macedonian kingship, and his defeat solidified Roman hegemony over Greece.
