Atmospheric pressure 0 kPa Himalia (hye-mal'-ee-ə, also hi-mahl'-ee-ə, ; Greek Ἱμαλíα) is a moon of Jupiter. It was discovered by Charles Dillon Perrine at the Lick Observatory in 1904 and is named after the nymph Himalia who bore three sons of Zeus.

On December 19, 2000, the Cassini spacecraft, en route to Saturn, captured a very low resolution image of Himalia, but it was too distant to show any surface details.

Himalia did not receive its present name until 1975; before then, it was simply known as Jupiter VI. It was sometimes called "Hestia".

It is the largest member of the group that bears its name, five moons orbiting between 11 and 13 Gm from Jupiter at an inclination of about 27.5°.
