Eukelade , also known as , is a retrograde irregular satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaiʻi led by Scott S. Sheppard in 2003, and received the temporary designation .IAUC 8087: Satellites of Jupiter 2003 March 4 (discovery)MPEC 2003-E11: S/2003 J 1, 2003 J 2, 2003 J 3, 2003 J 4, 2003 J 5, 2003 J 6, 2003 J 7 2003 March 4 (discovery and ephemeris)MPEC 2003-E29: S/2003 J 9, 2003 J 10, 2003 J 11, 2003 J 12; S/2003 J 1, 2003 J 6 2003 April 3 (revised ephemeris)
Eukelade is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 22.5 million km in 689 days, at an inclination of 165° to the ecliptic, in a retrograde direction and with an eccentricity of 0.363. Eukelade came to apojove (farthest distance from Jupiter) on 17 January 2026 when it was from Jupiter.
It was named in March 2005 after Eucelade - according to John Tzetzes, listed by some (unnamed) Greek writers as one of the Muses.* Marta Cardin, Olga Tribulato: Enumerating the Muses: Tzetzes in Hes. Op. 1 and the Parody of Catalogic Poetry in Epicharmus.

Supplementary Volumes 73). De Gruyter, Berlin/Boston 2019, pages 161–192; here page 171. The name ends in an "e" because the orbit is retrograde.
Eukelade belongs to the Carme group, made up of irregular retrograde moons orbiting Jupiter at a distance ranging between 23 and 24 million km and at an inclination of about 165°.
