Nellie Belle is a 2015 children's picture book by Mem Fox and illustrated by Mike Austin.

It is about a dog called Nellie Belle who escapes from her yard and has some adventures in her beachside town before being scared by some possums in a park and returning home.

Kirkus Reviews, on reviewing Nellie Belle, wrote: "Sunny, reassuring fare for recent graduates from toddlerdom itching to leave safe harbors (for a time, at least) to check out new horizons of their own".

[1] Publishers Weekly found it "an energetic, romping story from start to finish, yet counterbalanced by the soothing repetitions and rhythms of Fox’s verse".

[2] Nellie Belle has also been reviewed by the following magazines: Booklist,[3] School Library Journal,[4] Horn Book Guides,[5] and Magpies.
