佩尔狄卡斯，又译帕迪卡斯（希腊语：Περδίκας；？－前320年）是亚历山大大帝麾下主要将领之一，亦跟随亚历山大从事远征，成为大帝重要的左右手之一。在前323年在亚历山大临死前把象征王权的戒指给他，使他成为新国王腓力三世和亚历山大四世的帝国摄政，是亚历山大继业者之一。当佩尔狄卡斯掌权不久，原先亚历山大大帝的将领们开始策画夺取权位，佩尔狄卡斯是第一位试图保持帝国完整的继业者，但他与公主克丽奥佩脱拉的婚约导致被其他将领们怀疑他想自立为王，终使他与其他马其顿重要领导人安提帕特、克拉特鲁斯、埃及的托勒密交战。

Perdiccas (Greek:Περδίκκας, Perdikkas; c. 355 BC – c. 320 BC) was a general in Alexander the Great's army and participated in Alexander's campaign against Persia. Following Alexander's death, he was regent for Alexander's half brother and intellectually disabled successor, Philip Arridaeus (Philip III). As such, he was the first of the Diadochi who fought for control over Alexander's empire. In his attempts to establish a power base and stay in control of the empire, he managed to make enemies of key generals in the Macedonian army: Antipater, Craterus and Antigonus Monophtalmus, who decided to revolt against the regent. In response to this formidable coalition and a provocation from another general, Ptolomy, Perdiccas invaded Egypt, but when the invasion foundered his soldiers revolted and killed him.
