神名（英语：theonym），某个神明的专有名字。研究神名，是专有名词学中的重要分支。

英语theonym源自于古希腊语：theos，意为“神明”，后缀-onym，原意为名字。研究各个社会中尊崇的神明名字，可以了解他们语言的起源，也可以了解他们对这位特定神明的观点，从而了解他们的世界观。在印欧语的研究中，研究神名也是一个重要课题，经由研究同一语系中的神名变化，可以了解不同社区之间的关系。

A theonym (from classical Greek theos "god" and -onym "name") is a proper name of a deity. The study of theonyms is a branch of onomastics. The names of a society's gods may be useful in understanding the origin of their languages as well as their views of a particular deity. Theonyms have been useful in understanding the connections of Indo-European languages. Ancient Rigveda has multiple theonyms.
