Gadget & the Gadgetinis is an animated television series and the sequel of the 1983 series Inspector Gadget. The series was a co-production between Fox Kids Europe, DIC Entertainment Corporation, French animation studio SIP Animation, French broadcaster M6 Métropole Télévision, the British Channel 5 and the Italian Mediatrade S.p.A.

Gadget & the Gadgetinis is currently a property of WildBrain, which holds the rights to most of DIC's library. The show was first screened at MIPTV 2002. Despite being co-produced in the United States, it never aired in that country.

Having been recruited by an elite international peacekeeping group called the World Organization of Mega Powers (or WOMP for short), Lieutenant Gadget (promoted from his previous position of Inspector) now fights crime with a pair of mechanical assistants called the Gadgetinis, small robot versions of Gadget who were created by Penny (due to Brain retiring from active duty) and who are the unintended victims of Gadget's clumsiness.

As a member of WOMP, Lieutenant Gadget and his Gadgetinis still have to tangle with Doctor Claw and his organization M.A.D.

The original creators of Inspector Gadget reunited for this series. Andy Heyward initiated the concept and was one of the executive producers; Jean Chalopin created/developed the show and wrote or co-wrote every episode; while Bruno Bianchi designed the main characters as well as directing and producing the series. Gadget & the Gadgetinis follows basically the same plot as the original series, with the clueless Gadget attempting to fight crime while Penny and her helpers do all the work and he takes full credit for it, when he had no idea what happened. Dr. Claw appears less frequently and there are new villains for the group to contend with. Each episode would be budgeted at approximately $400,000 per episode. Saban was originally intended to distribute internationally Gadget & the Gadgetinis. There were also going to be more Gadgetinis as the show would progress.

While Brain and Chief Quimby are mainly absent from the show, they do appear in pictures in Gadget's house. Each also appears as a special guest in one episode. Brain appears in episode 36, "No Brainer", which reveals that, having been traumatized after years of pain while saving Gadget and Gadget mistaking him for M.A.D. Agents, he retired from crime-fighting to live in a riverside house, which only Penny knows about. The mere mention of the word "gadget" is enough to drive him frantic. Brain is also mentioned in the episode "Roverre". Chief Quimby appears in episode 45, "Super Boss Gadget". They both appear on television in the episode "Too Many Gadgets".

The French end credits to the series show a series of sketches of Penny going to visit Brain at his riverside home. The pair enjoy an emotional reunion.

Maurice LaMarche continued as Gadget's voice, reprising his role from the Sunday Movie Toon, "Inspector Gadget's Last Case", as did Brian Drummond (Dr. Claw) and Tegan Moss (Penny).
