What are the names of all four witches in Wizard

You're likely thinking of the movie "The Wizard of Oz," not "Wizard." There are actually three witches in that film:

* Glinda the Good Witch of the North: Played by Billie Burke.

* The Wicked Witch of the West: Played by Margaret Hamilton.

* The Wicked Witch of the East: This witch is not seen onscreen, but her house falls on the Wicked Witch of the West.

There is no fourth witch mentioned in the original book or movie.
