Leda Template:IPAc-en, also known as Template:Nowrap, is a prograde irregular satellite of Jupiter. It was discovered by Charles T. Kowal at the Mount Palomar Observatory on September 14, 1974, after three nights' worth of photographic plates had been taken (September 11 through 13; Leda appears on all of them).<ref name="Kowal1974"/><ref name="IAUC 2702">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It was named after Leda, who was raped<ref>Leda and the Swan</ref> by Zeus, the Greek equivalent of Jupiter (who came to her in the form of a swan). Kowal suggested the name and the IAU endorsed it in 1975.<ref name="IAUC 2846">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Leda belongs to the Himalia group, moons orbiting between 11 and 13 Gm from Jupiter at an inclination of about 27.5°.<ref name="Jacobson 2000">Template:Cite journal</ref> The orbital elements given here are as of January 2021, but they are continuously changing due to solar and planetary perturbations.
