Miss Lulu Bett is a 1920 novel by American writer Zona Gale, later adapted for the stage.

It was a bestseller at the time of its initial publication, but gradually fell out of favor through changing tastes and social conditions.

While joking around one evening they find themselves accidentally married, due to the laws of the state requiring little more than wedding vows to be recited while a magistrate is in the room for a marriage to count as legal.

Lulu eventually has to prevent Di from eloping, and is finally inspired to move out of her sister's home and live independently.

In 1921 the work was adapted for a silent film of the same name by Clara Beranger, directed by William C. deMille, starring Lois Wilson, Milton Sills, Theodore Roberts, Helen Ferguson, Mabel Van Buren, Ethel Wales and May Giraci.
