Charmville is the name of the town where most of the stories take place.

It is unclear if the name is related to the surname of the enchantress Mrs. Charming (the mother of Hazel, the series' central character) who appears to serve in a leading position for solving many problems.

The name reflects the vocabulary used by the central trio of girls called "Charmers" who use words like "Charmtastic" or "Charmazing" to describe things.
