Kari or Saturn XLV is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on 26 June 2006 from observations taken between January and April 2006.

Kari is about 7 kilometres in diameter, and orbits Saturn at an average distance of 22,305,100 km in 1243.71 days, at an inclination of 148.4° to the ecliptic (151.5° to Saturn's equator), in a retrograde direction and with an eccentricity of 0.3405. The rotation period has been determined to be 7.7±0.14 hours.

It was named in April 2007 after Kári, son of Fornjót, the personification of wind in Norse mythology.
