Fraggle Rock  is a children's puppet television series about interconnected societies of Muppet creatures, created by Jim Henson.

An international co-production of Canada, the United Kingdom and the United States, Fraggle Rock was co-produced by British television company Television South (TVS), the Canadian Broadcasting Corporation (CBC), U.S. pay television service  (HBO) and Henson Associates. Unlike Sesame Street, which had been created for a single market and later adapted for international markets, Fraggle Rock was intended from the start to be an international production, and the entire show was constructed with this in mind.

In 2020, a reboot of Fraggle Rock was ordered by Apple TV+.

There are four main intelligent anthropomorphic species in the Fraggle Rock environment: Fraggles, Doozers, Gorgs and Silly Creatures. The Fraggles and Doozers live in a system of natural caves called Fraggle Rock that are filled with all manner of creatures and features and which connect to at least two different areas:

One of the main themes of the series is that, although the three species depend on the other for their survival, they usually fail to communicate due to vast differences in their biology and culture. The series mainly follows the adventures of five Fraggles, each with their own personality: pragmatic Gobo, artistic Mokey, indecisive Wembley, superstitious Boober, and adventurous Red. Some of the characters' names are film industry in-jokes. For example, Uncle Travelling Matt is a reference to the travelling matte technique used with blue screen to give the impression a character is somewhere they are not; Gobo is named after a shaped metal grill placed over a theatre light to produce interesting shadows (window shapes, leaves etc.) and Red is a reference to a "redhead".

Fraggles are small anthropomorphic creatures, typically 22 inches (56 cm) tall, that come in a variety of colors and have fur tuft tipped tails. Fraggles live a generally carefree life, spending most of their time (they have a thirty-minute work week) playing, exploring, and generally enjoying themselves. They live on mainly radishes and Doozer sticks, made of ground-up radishes and the material with which the Doozers build their constructions. The Fraggles seek wisdom from Marjory the Trash Heap, who is located in a corner of the Gorgs' garden. Marjory the Trash Heap is a large, matronly, sentient compost heap. According to her rat-like companions Philo and Gunge, the Trash Heap "knows all and sees all." By her own admission, she has "everything".

Within Fraggle Rock lives a second species of small humanoid creatures, the pudgy, green and industrious Doozers. Standing about 6 inches (15 cm) tall ("knee-high to a Fraggle"). Doozers are in a sense the opposite of Fraggles; their lives are dedicated to work and industry. Doozers spend much of their time busily constructing all manner of scaffolding throughout Fraggle Rock, using miniature construction equipment and wearing hardhats and work boots. Doozers build their constructions out of an edible candy-like substance (manufactured from radishes) which is greatly enjoyed by Fraggles. This is essentially the only interaction between Doozers and Fraggles; Doozers spend most of their time building just for the sake of it, and Fraggles spend much of their time eating Doozer buildings which they consider delicious. The Doozers say in an early episode that "architecture is meant to be enjoyed", and in "The Preachification of Convincing John" Mokey prevents the other Fraggles from eating the building work, believing it to be insensitive to the Doozers. As a result, the Doozer building eventually takes over Fraggle rock, and once full the Doozers plan on moving out as they have nowhere left to build. They explain that they want the Fraggles to eat their work in order to create space for more building work to go up again. Despite this co-dependence, the Doozers generally maintain a low opinion of Fraggles, considering them frivolous. The Doozers also seem to have little knowledge of the universe outside Fraggle Rock; early in the series they are unaware of the existence of the Gorgs or their garden.

Outside another exit from Fraggle Rock live a small family of Gorgs, fat furry humanoids standing about 264 inches (670 cm). The husband and wife of the family, Pa and Ma, consider themselves the King and Queen of the Universe, with their son Junior Gorg as its prince and heir-apparent, but to all appearances they are simple farmers with a rustic house and garden patch. In "The Gorg Who Would be King", Pa says he has ruled for 742 years.

Fraggles are considered pests by the Gorgs, as they often steal radishes from the garden. The Fraggles do not consider it stealing. The Gorgs use the radishes to make anti-vanishing cream, without which they disappear headfirst.
