Noonday (spelled Noon Day on 1860s maps) was an unincorporated community located in far north-central Cobb County, Georgia. It was centered at 34°03'43"N, 84°31'16"W (34.0620437, -84.5213204), along former Georgia highway 5, around the Noonday Baptist Church. This Baptist church is still active today. Little Noonday Creek runs just south of there, into Noonday Creek just to the west.
