Alpharetta is a city in north Fulton County, Georgia, United States. The city is a northern suburb of Atlanta. According to the 2010 Census, Alpharetta's population is 57,551.

From the North Georgia Mountains to the Chattahoochee River along a Cherokee Indian trail, a tiny village named New Prospect Camp Ground was formed. This village, made up of tents, a log school, and arbor became a trading post where Indians and white settlers exchanged their goods. The surrounding countryside provided excellent farming land, especially for cotton. On December 11, 1858, the town was chartered and became the county seat of Milton County. Alpharetta's city website states the name is a combination of the Greek words for "first" and "town", however "town" in Greek is "Poli" or "Polis" and "Retta" is not even a Greek word. Officially chartered on December 11 of that year, Alpharetta served as the county seat of Milton County until the end of 1931 when Milton was merged with Fulton County to avoid bankruptcy during the Great Depression.
