Barney's Trick or Treat! is a 1997 children's picture book that was written by Mark S. Bernthal and illustrated by Bill Alger.
It's Halloween, and Barney, BJ and Baby Bop are ready to howl! But a frisky puppy nearly spoils Baby Bop's trick-or-treat bag and the young dino pals learn a lesson in neighborly kindness when the evening ends surprisingly at a "sorta spooky" house.
- This is the second time Scooter, the puppy, appears in a book after BJ and Scooter.
- This book was included in the treasury of Barney's Favorite Halloween Stories.
