Orthosie /ɔːrˈθoʊziː/, also known as Jupiter XXXV, is a natural satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2001, and given the temporary designation S/2001 J 9.^[7]^[1]

Orthosie is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 21,075,662 km in 625.07 days, at an inclination of 146.46° to the ecliptic (143° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.3376.^[8]

It was named in August 2003 after Orthosie, the Greek goddess of prosperity and one of the Horae.^[9] The Horae (Hours) were daughters of Zeus and Themis.

Orthosie belongs to the Ananke group.
