Ancient Fraggles are the prehistoric counterparts of modern Fraggles. They occupy the same caves as modern Fraggles do. They are seen in Episode 508: Mokey Then and Now. Unlike modern Fraggles, Ancient Fraggles submit to the authority of a ruler - Fishface Fraggle. Other key differences are Ancient Fraggles are usually serious, don't laugh or play games and are bald (thus they find having hair as one of the funniest things possible).

The named Ancient Fraggles are:

• Fishface Fraggle (Jerry Nelson)
• Bonehead Fraggle (Cheryl Wagner)
• Bigmouth Fraggle (Bob Stutt)
• Noodlenose Fraggle (Tim Gosley)
