Thyone or Jupiter XXIX, is a non-spherical moon of Jupiter. It was found by a team of astronomers from the University of Hawaii led by Scott S. Sheppard, et al. in 2001, and given the designation S/2001 J 2.

Thyone is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 21.406.000 km in 639.803 days, at an inclination of 147° to the ecliptic 147° to Jupiters equator with an orbital eccentricity of 0.2526.

It was named in August 2003 after Thyone, better known as Semele, one of Zeus conquests in Greek mythology.

Thyone belongs to the Ananke group, retrograde non-spherical moons which orbit Jupiter between 19.300.000 and 22.700.000 km, at inclinations of about 150°.
