Philip (Greek: Φίλιππος, died about 328 BC) was a Macedonian soldier under Alexander the Great.

Philip was the youngest of four sons born to Agathocles^[1][2] and his wife, possibly named Arsinoe. His paternal grandfather may have been called Alcimachus and one of his brothers was Lysimachus, one of the Diadochi of Alexander the Great.^[3]

His father was a nobleman of high rank who was a close friend and advisor of King Philip II of Macedon and became a favourite in the Argead court.^[4] Philip and his brothers grew up being regarded as Macedonians. Philip and his brothers enjoyed prominent positions in King Alexander the Great’s circle^[5] and they were educated at the court at Pella.^[6]

Philip and his brothers served as a royal Hypaspists^[7] in the service of Alexander. Not long after the death of Cleitus the Black, Philip accompanied Alexander on foot, refusing the mount of Lysimachus’ horse who rode nearby.^[8] He remained near Alexander’s side, both in the pursuit of the supporters of Spitamenes, his Sogdian rebels and their cavalry.^[9] Philip finally collapsed from exhaustion and died in Alexander’s arms.^[10][11] In his military actions, Philip was trying to emulate his second eldest brother, Lysimachus.^[12]
