Alexander IV of Macedon, (lived 323 - 309 BC; titular King of Macedon, 323 - 309 BC), the posthumous son of Alexander the Great by his wife Roxana, a princess of Bactria, was born in 323 BC, a few months after his father's death and was immediately declared King as co-ruler with his uncle Philip III of Macedon. Neither King wielded any political influence: Philip was considered retarded and Alexander was just a infant. This resulted in the nomination of Regents ruling on their behalf and a number of his father's generals, now Satraps of major provinces, gaining enough power to act independently from the crown.
- Perdiccas, between 323 BC and his murder in June, 321 BC.
- Antipater, between the summer of 321 BC and the summer of 319 BC when he died of illness.
- Polyperchon, between 319 BC and 316 BC, a heir chosen by Antipater himself. Olympias, Alexander's grandmother, exerted considerable influence over Polyperchon and ordered the execution of Philip III in 317 BC.
- Cassander, Antipater's son, defeated Polyperchon's armies and captured and executed Olympias. Between 316 BC and 309 BC the Regent Cassander held the young King Alexander as a prisoner.
