The New Scooby-Doo Movies was the second series in the Scooby-Doo franchise and the only hour-long entry, running for two seasons on CBS from 1972 to 1973 with 24 episodes produced.

This was the franchise's last time featuring Nicole Jaffe as the regular voice of Velma Dinkley, as she retired from acting following her marriage.

Many guest stars provided their own voices, including Don Knotts, Jerry Reed, Cass Elliot, Jonathan Winters, Sandy Duncan, Tim Conway, Dick Van Dyke, Don Adams, Davy Jones and Sonny & Cher, while deceased or retired celebrities like The Three Stooges and Laurel and Hardy were voiced by imitators.

The Addams Family and Batman and Robin both appeared on the show a year before being incorporated into their own dedicated Hanna-Barbera series, The Addams Family and Super Friends respectively; this also marked the first appearance of Batman and Robin in a Hanna-Barbera cartoon.

The first season was animated at Hanna-Barbera's main studio in Los Angeles, while the second season was produced at their newly formed studio, Hanna-Barbera Pty, Ltd., in Australia.

When attempting to release a complete DVD set in 2005, Warner Home Video could not negotiate rights with several guest stars, resulting in a truncated release titled The Best of the New Scooby-Doo Movies featuring only 15 of the 24 episodes, with opening titles edited to remove images of the Addams Family, Batman and Robin, the Harlem Globetrotters, and the Three Stooges and Laurel and Hardy.

The episode 'Wednesday Is Missing,' featuring the Addams Family, remains the only episode of the series that has never been released or announced for release on DVD.

Like many Hanna-Barbera series of the 1970s, the show used a studio-created laugh track.
