Brats of the Lost Nebula is a Canadian science fiction puppet computer-animated television series for kids. The series follows five orphaned children from different war-torn planets. As they search for their surviving family members, they must also band together to fight an evil invading force known as "The Shock".

The series was created by Dan Clark, who was also an executive producer along with Brian Henson and Margaret Loesch. The puppet characters mixed both traditional hand puppetry and animatronics. These puppets were built by Jim Henson's Creature Shop. The computer graphics were created by C.O.R.E. Digital Effects.

In the United States, the series aired on The WB during the Kids' WB block in October 1998, being one of the only two live-action shows (the other being The Nightmare Room) that were ever aired on that channel. It was removed from the channel after airing its third episode.^[1] The remaining episodes were shown on Canada's YTV channel.

The Brats, sometimes referred to as orphans, each have a different set of skills in addition to their otherworldly uniqueness. After the escape of Zadam and Triply from the Shock attack on their home world, the five kids meet on a living planetoid to start their rebellion against The Shock and find their lost parents.
