赫卡忒（希腊语：Ἑκάτη、拉丁语：Hecate）是希腊神话中前奥林匹亚的一个重要的提坦女神，也是象征着暗月之夜的“月阴女神”或“黑月女神”。

赫卡忒总是和下弦月、夜晚、鬼魂、阴间、精灵、魔法、巫术和招魂术联系在一起。她是著名的不可抗拒的死神，无法战胜或无人能及的女皇，同样也是妖术、魔咒和女巫的守护女神。赫卡忒是一位具有强**力的女神，她曾经帮助宙斯打败过独眼巨人，所以她有着巨人一般的强大力量，即使是众神之王宙斯也都敬畏赫卡特女神。赫卡忒可能起源于古埃及的青蛙女神海奎特或是来自于亚细亚的西南地区，并且掌控着所有三岔路的交叉口，她总会在子夜时分出现在鬼魂前往阴间必经的三岔路口，高举着火炬指引鬼魂通往阴间。

Hecate or Hekate (/ˈhɛkətiː, ˈhɛkɪt/; Greek Ἑκάτη, Hekátē) is a goddess in Ancient Greek religion and mythology, most often shown holding two torches or a key and in later periods depicted in triple form. She was variously associated with crossroads, entrance-ways, dogs, light, the moon, magic, witchcraft, knowledge of herbs and poisonous plants, ghosts, necromancy, and sorcery. In the post-Christian writings of the Chaldean Oracles (2nd–3rd century CE) she was regarded with (some) rulership over earth, sea and sky, as well as a more universal role as Saviour (Soteira), Mother of Angels and the Cosmic World Soul. She was one of the main deities worshiped in Athenian households as a protective goddess and one who bestowed prosperity and daily blessings on the family.
