Rohini is the 4th of the 27 nakshatras, the lunar mansions of Indian astronomy. It spans 10°00′ Vrishabha to 23°20′ Vrishabha of the sidereal zodiac. Its name means "the red one", its presiding deity is Prajapati, the lord of creatures and progenitor, and its planetary lord in the Vimśottarī system is Moon.

The span is calculated with the Lahiri ayanamsa. The name, deity, lord and junction star are traditional and cited below; they describe a cultural system, not a measured influence.
