Alpharetta is a city in northern Fulton County, Georgia, United States, and part of the Atlanta metropolitan area. As of the 2020 U.S. census, Alpharetta's population was 65,818; in 2010, the population had been 57,551.

In the 1830s, the Cherokee people in Georgia and elsewhere in the South were forcibly relocated to the Indian Territory (present-day Oklahoma) under the Indian Removal Act. Pioneers and farmers later settled on the newly vacated land, situated along a former Cherokee trail stretching from the North Georgia mountains to the Chattahoochee River.

One of the area's first permanent landmarks was the New Prospect Camp Ground (also known as the Methodist Camp Ground), beside a natural spring near what is now downtown Alpharetta. It later served as a trading post for the exchanging of goods among settlers.

Known as the town of Milton through July 1858, the city of Alpharetta was chartered on December 11, 1858, with boundaries extending in a 0.5-mile (0.8 km) radius from the city courthouse. It served as the county seat of Milton County until 1931, when Milton County merged with Fulton County to avoid bankruptcy during the Great Depression.

The city's name may be a variation of a fictional Indian girl, Alfarata, in the 19th-century song "The Blue Juniata"; it may also be derived from alpha, the first letter of the Greek alphabet.

The Simeon and Jane Rucker Log House, built in 1833, was listed on the National Register of Historic Places in 1997.

The inhabitants of the area, primarily Methodists and Baptists, engaged in various occupations such as farming, blacksmithing, milling, merchandising, carpentry, and ditching. A number of them possessed a small number of slaves. Throughout the American Civil War (1861-65), local men participated in combat or served in the home guard; however, Union forces did not advance north of Roswell, which is situated roughly six miles to the southwest.

Alpharetta is in northern Fulton County and is bordered to the southeast by Johns Creek, to the south and west by Roswell, to the north by Milton, and to the northeast by unincorporated land in Forsyth County. Downtown Alpharetta is 26 miles (42 km) north of downtown Atlanta.

According to the United States Census Bureau, Alpharetta has an area of 27.3 square miles (70.7 km), of which 26.9 square miles (69.7 km) is land and 0.39 square miles (1.0 km), or 1.37%, is water.
