A person from Chattanooga, Tennessee, a city in the southeastern United States.
From Chattanooga (derived from Cherokee meaning 'rock coming out of the water') plus the suffix -an meaning 'a person from.' The base place name comes from Native American origins reflecting the geography.
Chattanooga's name survived colonization because it was a major city, but the Cherokee meaning got displaced—we say 'Chattanoogan' without knowing the name literally describes the landscape that mattered to people there first.
