乌莎斯（उषः；uṣás-），梵语中曙光、黎明之意，吠陀教时代登场的提毗神祇（乌莎斯有时亦会被想像成多个复数体存在），梨俱吠陀1028首赞美诗中就有20首是献给她的。她是天父神特尤斯的女儿，以漂亮性感打扮的形象骑乘着战车出现。乌莎斯是-s后缀，即是说其属格变格是uṣásas，这是原于原始印欧语的en:Hausos，与希腊语的Ηως（厄俄斯，或罗马对应的Aurora）是同源词，三者都是象征曙光与光芒的女神之名字。

Ushas (उषस्; uṣas), Sanskrit for "dawn", is a Vedic deity, and consequently a Hindu deity as well.

Ushas is an exalted goddess in the Rig Veda but less prominent in post-Rigvedic texts. She is often spoken of in the plural, "the Dawns." She is portrayed as warding off evil spirits of the night, and as a beautifully adorned young woman riding in a golden chariot on her path across the sky. Due to her color she is often identified with the reddish cows, and both are released by Indra from the Vala cave at the beginning of time.
