阿佩普（Apophis），又译阿波菲斯，是埃及神话中的神，被认为是破坏、混沌、黑暗的化身，也是太阳神「拉」的孪生兄弟以及死对头。他希望世间陷入永久的黑暗。一般他的形象是一条蛇。有一颗小行星以他命名。

Apep (/ˈæˌpɛp/ or /ˈɑːˌpɛp/) or Apophis (/ˈæpəfᵻs/; Ancient Greek: Ἄποφις; also spelled Apepi or Aapep) was the ancient Egyptian deity who embodied chaos (ı͗zft in Egyptian) and was thus the opponent of light and Ma'at (order/truth). He appears in art as a giant serpent. His name is reconstructed by Egyptologists as *ʻAʼpāpī, as it was written ꜥꜣpp(y) and survived in later Coptic as Ⲁⲫⲱⲫ Aphōph. Apep was first mentioned in the Eighth Dynasty, and he was honored in the names of the Fourteenth Dynasty king 'Apepi and of the Greater Hyksos king Apophis.
