Father Goose's Year Book: Quaint Quacks and Feathered Shafts for Mature Children is a collection of humorous nonsense poetry written by L. Frank Baum, author of the Oz books.

The book was illustrated by Walter J. Enright; he was the husband of Maginel Wright Enright, the artist who illustrated Baum's The Twinkle Tales (1906), Policeman Bluejay (1907), and L. Frank Baum's Juvenile Speaker (1910).

As its title indicates, Father Goose's Year Book was an attempt to capitalize on the prior success of Father Goose: His Book, the 1899 collaboration between Baum and W. W. Denslow that was the dominant best-seller in children's literature at the turn of the twentieth century.

[2] The Year Book was a belated version of the calendar: it was a date book with humorous poems and pictures on the left (the verso side of each leaf), faced with blank pages on the right (the recto side) for making notes.

Baum's poems for the collection are similar to his verses in the original Father Goose, but aimed at adults (the "mature children" of the subtitle).
