Ymir (/[unsupported input]ˈɪmɪər/ IM-eer), or Saturn XIX is a moon of Saturn. It was found by Brett J. Gladman, et al. in 2000, and given the designation S/2000 S 1. It was named in August 2003, from Norse mythology, where Ymir is the ancestor of all the Jotuns or frost giants.

Ymir is about 16 kilometres in diameter, and orbits Saturn at an average distance of 23,175,000 km in 1317.137 days, at an inclination of 172° to the ecliptic (146° to Saturn's equator), with an eccentricity of 0.358.
