Hati (/ˈhɑːti/ HAH-tee) or Saturn XLIII (provisional designation S/2004 S 14) is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on 4 May 2005, from observations taken between 12 December 2004 and 11 March 2005.
Hati is about 6 kilometers in diameter, and orbits Saturn at an average distance of 20,303 Mm in 1080 days, at an inclination of 163° to the ecliptic (165° to Saturn's equator), in a retrograde direction and with an eccentricity of 0.291. In March 2013, the synodic rotational period was measured by Cassini to about 5.5 hours. This is the fastest known rotation of all of Saturn's moons.
It was named in April 2007 after Hati, a giant wolf from Norse mythology, son of Fenrisúlfr and twin brother of Sköll.
