Svati is the 15th of the 27 nakshatras, the lunar mansions of Indian astronomy. It spans 6°40′ Tula to 20°00′ Tula of the sidereal zodiac. Its name means "the independent one", its presiding deity is Vayu, the wind, and its planetary lord in the Vimśottarī system is Rahu.

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.

The other Rahu mansions

The nine lords repeat three times around the zodiac, so each lord rules three mansions, 120° apart.
