The Kingdom of Pergamon, Pergamene Kingdom, or Attalid kingdom was a Greek state during the Hellenistic period that ruled much of the Western part of Asia Minor from its capital city of Pergamon. It was ruled by the Attalid dynasty (/ˈætəlɪd/; Greek: Δυναστεία των Ατταλιδών, romanized: Dynasteía ton Attalidón).

The kingdom was a rump state that was created from the territory ruled by Lysimachus, a general of Alexander the Great. Philetaerus, one of Lysimachus' lieutenants, rebelled and took the city of Pergamon and its environs with him; Lysimachus died soon after in 281 BC. The new kingdom was initially in a vassal-like relationship of nominal fealty to the Seleucid Empire, but exercised considerable autonomy and soon became entirely independent. It was a monarchy ruled by Philetaerus's extended family and their descendants. It lasted around 150 years before being eventually absorbed by the Roman Republic during the period from 133–129 BC.
