On National Scooby-Doo Day, Scooby-Doo fans get their moment each year when a special day takes place to honor their favorite crime-solving dog. The spotlight swings to that lovable pet that tackles spooky mysteries with Scooby snacks and teamwork.

National Scooby-Doo Day marks the debut of Scooby-Doo, Where Are You!, which first aired on September 13, 1969. That Saturday morning cartoon quickly became a favorite, known for its spooky stories, funny characters, and classic catchphrases. Scooby and his crew brought something different — lighthearted scares, smart clues, and plenty of laughs.

No government group or major company officially created National Scooby-Doo Day. It grew from fan support and online buzz. Over time, blogs, pet websites, and pop culture pages began highlighting the date.

The animated series Scooby-Doo, Where Are You! centers on four teenage friends, Fred Jones, Daphne Blake, Velma Dinkley, and Norville ‘Shaggy’ Rogers, along with their talking dog, Scooby-Doo. The crew travel around in their van called The Mystery Machine, solving strange, spooky, and hilariously kooky mysteries. The show was created by the legendary Hanna-Barbera animation studio founders William Hanna and Joseph Barbera, along with Joe Ruby. The series featured Nicole Jaffe as the voice of Velma Dinkley, Casey Kasem as the voice of Norville ‘Shaggy’ Rogers, Don Messick as the voice of Scooby-Doo, Stefanianna Christopherson as the voice of Daphne Blake, Frank Welker as the voice of Fred Jones, Hal Smith as the voice of Cosgood Creeps, Heather North as the voice of Daphne Blake, John Stephenson as the voice of Big Bob Oakley, and Barry Richards as the voice of The Ghost Clown, along with Vic Perrin and Jean Vander Pyl.
