菲迪亚斯（Phidias 或 Pheidias，古希腊文：Φειδίας，约公元前480年－前430年）是古希腊的雕刻家、画家和建筑师，被公认为最伟大的古典雕刻家。雅典人。

其著名作品为世界七大奇迹之一的宙斯巨像和巴特农神殿的雅典娜巨像，两者虽然都早已被毁，不过有许多古代复制品传世，其中的雅典娜巨像甚至在二十世纪末，在美国有人做出1:1尺寸的翻版品（请参看雅典娜·帕德嫩条目）。

据说巴特农神殿的装饰雕刻，也是在他领导设计和监督下完成的，这些装饰雕刻主要藏于伦敦不列颠博物馆，被认为是古希腊雕刻全盛时期的代表作。

Phidias or Pheidias (/ˈfɪdiəs/; Greek: Φειδίας, Pheidias; c. 480 – 430 BC) was a Greek sculptor, painter and architect. His statue of Zeus at Olympia was one of the Seven Wonders of the Ancient World. Phidias also designed the statues of the goddess Athena on the Athenian Acropolis, namely the Athena Parthenos inside the Parthenon, and the Athena Promachos, a colossal bronze statue of Athena which stood between it and the Propylaea, a monumental gateway that served as the entrance to the Acropolis in Athens. Phidias was the son of Charmides of Athens. The ancients believed that his masters were Hegias and Ageladas.
