Hati (pronEng|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 May 4, 2005, from observations taken between December 12, 2004, and March 11, 2005.

Hati is about 6 kilometers in diameter, and orbits Saturn at an average distance of 20,303 Mm in 1080.099 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.
