金固（英语：Kingu），是美索不达米亚神话的神明，意思为「无技术劳动者」，为迪亚马特的儿子与第二任丈夫，最后被马尔杜克所杀。

在民科撒迦利亚·西琴的《地球编年史》被当成月球的原称，为迪亚马特一颗最重要的卫星。小说中说，金固于一次天体碰撞中幸免于难。后来，迪亚马特被尼比鲁一分为二后，金固跟随了地球(迪亚马特的转世)，然后被北风(尼比鲁的一颗卫星)击中，小了一个尺寸，成为现在的月亮。它亦被称为迪亚马特的守护者。月神(sin)这个名字的意思为沦陷地之主。

Kingu, also spelled Qingu, meaning "unskilled laborer," was a god in Babylonian mythology, and — after the murder of his father Abzu — the consort of the goddess Tiamat, his mother, who wanted to establish him as ruler and leader of all gods before she was killed by Marduk. Tiamat gave Kingu the 3 Tablets of Destiny, which he wore as a breastplate and which gave him great power. She placed him as the general of her army. However, like Tiamat, Kingu was eventually killed by Marduk. Marduk mixed Kingu's blood with earth and used the clay to mold the first human beings, while Tiamat's body created the earth and the skies. Kingu then went to live in the underworld kingdom of Ereshkigal, along with the other deities who had sided with Tiamat.
