Mildred Hubble - Young apprentice witch featured on the British fantasy comedy THE WORST WITCH/ITV/1998-2000 and the sequel series WEIRDSISTER COLLEGE: THE FURTHER ADVENTURES OF THE WORST WITCH/ITV/2001.

Mildred attends a special school for witches called Miss Cackle's Academy where she lives in a cold, windowless room with her cat, Tabby. Mildred earned a scholarship to the school by writing a creative essay. But, she herself was not born into a family of witches, but she aspires to master the arts of magic and earn her Witches Higher Certificate. And even though the school's gentle-nature headmistress, Miss Cackle, dubbed Mildred "The Worst Witch" she overlooks Mildred's mistakes because she sees that Mildred has the potential to be a truly good witch one day.

The first day of school Mildred started off on the wrong foot by flying into a bunch of dustbins. Luckily, she was rescued by fellow student Maud Moonshine, who along with Ruby, Enid Nightshade (a prankster) and Jadu Wali became her friends.

Mildred's nemesis is teacher's pet, Ethel Hallow. She belittled Mildred by telling her "You have to come from a witch family to be a real witch." Drusilla Paddock is Ethel's nasty sidekick.

The Academy staff consisted of Miss Cackle, the headmistress (Agatha is her evil twin sister), Miss Constance Hardbroom (a strict disciplinarian, former headmistress and potion mistress), Miss Davina Bat, (Chanting Teacher), Miss Imogen Drill (P.E. Teacher), Mrs. Tapioca (school cook), Edgar Hellibore, the Chief WIzard of Hellibore's Academy (a visiting professor), Algernon Rowan-Webb (a wizard in training who used to be a frog) and Mr. Blossom (the Handyman).

After passing her basic witch training, Mildred Hubble transferred to a special school for witches and wizards called Weirdsister College to further develop her unique and emerging abilities and hopefully learn to cope with her fear of the dark.
