大衮（天主教译为达贡）是闪米特人的一个主要的神，司农业，由早期阿摩利人所崇拜。祂的形状是一个披着鱼皮的男性，是非利士民族的众神之首，被信奉犹太教的以色列人认为是魔鬼。

概述： 在H·P·洛夫克拉夫特（H·P·Lovecraft）创造的克苏鲁神话（Cthulhu Mythos）体系中，大衮（Dagon，又译达贡）与雌性的许德拉（Mother Hydra）作为旧日支配者克苏鲁（Cthulhu）的从者而存在，它们为深潜者（Deep Ones）的首领、父神以及母神。有说法指出大衮与许德拉为较小型的下级旧日支配者，也有人认为它们只是长生的大型深潜者而已。

Dagon (Hebrew:דגון'‎, Tib. Dāḡôn) or Dagan (Ugaritic: Dgn, Dagnu, or Daganu; Akkadian: Dagana) was originally an East Semitic Mesopotamian (Akkadian, Assyrian, Babylonian) fertility god who evolved into a major Northwest Semitic god, reportedly of grain (as symbol of fertility) and fish and/or fishing (as symbol of multiplying). He was worshipped by the early Amorites and by the inhabitants of the cities of Ebla (modern Tell Mardikh, Syria) and Ugarit (modern Ras Shamra, Syria). He was also a major member, or perhaps head, of the pantheon of the Philistines.
