Arche /ˈɑːrkiː/, also known as Jupiter XLIII, is a natural satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaiʻi led by Scott S. Sheppard on 31 October 2002, and received the temporary designation S/2002 J 1.

Arche is about 3 kilometres in diameter, and orbits Jupiter at an average distance of 23,717,000 km in 746.185 days, at an inclination of 165° to the ecliptic (162° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.149.
