Jellia Jamb is a fictional character from the classic children's series of Oz books by American author L. Frank Baum.

She handles the separate rooms of Dorothy, the Scarecrow, Tin Woodman, and Cowardly Lion during their stay and upon their first visit to the city to see the great Wizard.

She leads Dorothy through seven hallways and up three grand staircases to her private chambers, and even provides the little girl with a fancy green dress made of brocaded satin.

All around her silken waist four leaf clovers are delicately sewn into the sash and she wears a little jacket trimmed with sparkling emeralds of a uniform size.

In The Shirley Temple Show's 1960 adaptation of The Land of Oz, she appears for the famous translation scene, and is depicted as a beautiful, yet comical young woman.

She served as one of servant of Wizard, but after the Scarecrow became ruler of Emerald City, she change name to Jinjur and became self-appointed general leading an all-woman force "Army of Revolt".

In the anime feature film The Wizard of Oz (1982), she is an unnamed young, tawny-haired girl voiced by Elizabeth Hanna, who is unbilled for that role, and dressed like a soldier instead of a maid.
