North Decatur is an unincorporated community and census-designated place (CDP) in DeKalb County, Georgia, United States.

An early settler in this part of DeKalb County was Chapman Powell, whose "Medicine House" cabin was built near 1218 Clairmont Road.

Dr. Powell (1798-1870) owned most of the land in the Candler Lake and South Fork Peachtree Creek area during his lifetime.

[4] Ezekiel Mason built a mill on the east side of Clairmont Road on Burnt Fork Creek.

Its proximity to Atlanta's Midtown and Buckhead districts, as well as Emory University and Decatur, makes it a desirable "in-town" location for what was originally developed as a suburban community.
