List of monarchs of Cappadocia

This article lists the Hellenistic princes and kings of Cappadocia, an ancient region in central Anatolia.

Independent princes of Cappadocia, 331 BC – 250s BC
The hitherto satrap, Ariarathes I managed to keep control of most or all Cappadocia, as independent prince leading the resistance against conquerors, even after Alexander the Great's conquest of the Persians; however, in 322 BC, he was crucified by Perdiccas, Alexander's general and (after Alexander's death) regent. Perdiccas gave Cappadocia to Eumenes, Alexander's former secretary. However, during the instability of the ongoing Wars of the Diadochi, Eumenes was killed, and then the regent Antigonos was killed.
 * Ariarathes I, 331–322 BC
 * temporary suppression of independence, governors of Macedon Empire held the country
 * governor Eumenes
 * diadoch Antigonos, firstly satrap of Phrygia and then Regent. He was killed in Ipsos in 301 BCE.

Ariarathes I's adopted son, Ariarathes II, managed to re-secure some of his inheritance, namely the mere Upper Cappadocia around Mazaca, and became Prince of Cappadocia (while accepting Seleucid suzerainty). The Lower Cappadocia was lost forever to Kingdom of Pontos which emerged since 301 BCE in the coast of Black Sea, and proclaimed Kingdom in circa 281 BCE.
