Mokey Fraggle is one of the five main Fraggles in Fraggle Rock. She has a pinkish purple skin and long turquoise hair, and she wears a long grey robe-like sweater.

Mokey is a dreamer. She loves painting, writing poems in her diary, or just enjoying her surroundings. Because she is the oldest of the Fraggle Five, she functions as the 'den mother' within the group. Mokey is very emotional and concerned about others. She's always ready to help a friend in need, even if it's a Gorg. Mokey's job is to pick radishes in the Gorgs' Garden.

Mokey shares a room with her best friend Red Fraggle. She has a soft spot for Gobo Fraggle, whom she thinks is very brave. She has a pet plant named Lanford.

Mokey was named after a childhood friend of Jim Henson. In the language of the ancient Fraggles, "Mokey" means "Put on your hat."

One of Mokey's unique features is her eyelids. Except for the revised Gobo puppet appearing after the show's first twelve episodes, she is the only Fraggle who has movable eyelids. In place they give her a dreamy look, but they can slide up to show surprise, astonishment, fear and intensity.
