What is Dorothy last name in Wizard of Oz?

Answer 1

Gale is the last name that Dorothy has in both the original 1900 book edition and the beloved 1939 film version of "The Wizard of Oz."

Specifically, Dorothy is presented as an orphan girl being raised by her Uncle Henry and Aunt Em. Dorothy's adoptive or foster parents are given no last name. There also is no explanation as to whether the elderly couple really is related to Dorothy and if so, in what way and on which side of the family.

But later on in the Royal Histories of Oz series, author and series originator Lyman Frank Baum (May 15, 1856 - May 6, 1919) has Uncle Henry speak of the strong resemblance between Dorothy and her mother. This may favor an interpretation of Uncle Henry as being the brother of Dorothy's mother.
