Scooby-Doo! Mystery Incorporated is mainly set in the fictional town of Crystal Cove.
Crystal Cove is presented as a community famous for supernatural sightings and unexplained events. That reputation gives Mystery Inc. a steady supply of cases while also supporting the series’ more serialized story. The town’s history is closely connected to earlier mystery-solving groups and to the larger mythology developed across the show.
The 2010 series differs from many earlier Scooby-Doo versions by giving its setting a stronger continuing identity. Characters, relationships, and clues develop across episodes instead of resetting completely after every mystery.
Coolsville is another location associated with parts of the Scooby-Doo franchise, so it is a common mix-up. Crystal Cove, however, is the central setting of Mystery Incorporated. The name also reinforces the show’s recurring contrast between a cheerful tourist town and its unsettling supernatural reputation.
