Nora Archibald Smith (1859–1934) was an American writer of children's literature in the late 19th and early 20th centuries, and sister of Kate Douglas Wiggin.
Both sisters were active in the kindergarten movement that was developing at the turn of the twentieth century, and wrote repeatedly on the subject.
She soon remarried and the family moved into Nora and Kate’s stepfather’s (Dr. Albion Bradbury) house in Hollis, Maine.
Kate opened the first free kindergarten west of the Rocky Mountains on Silver Street in San Francisco, California while Nora was teaching in the public schools of Tucson, Arizona.
Nora, a writer in her own right, also published many serial stories and academic journal articles on early childhood education.
