Macon (), officially Macon–Bibb County, is a consolidated city-county in the U.S. state of Georgia. Macon lies near the state's geographic center, about 85 miles (137 km) southeast of Atlanta—hence the city's nickname, "The Heart of Georgia".
Located near the fall line of the Ocmulgee River, Macon had a 2019 estimated population of 153,159. It is the principal city of the Macon Metropolitan Statistical Area, which had an estimated population of 228,914 in 2017. Macon is also the largest city in the Macon–Warner Robins Combined Statistical Area (CSA), a larger trading area with an estimated 420,693 residents in 2017; the CSA abuts the Atlanta metropolitan area just to the north.
In a 2012 referendum, voters approved the consolidation of the governments of the City of Macon and Bibb County, and Macon became Georgia's fourth-largest city (just after Columbus). The two governments officially merged on January 1, 2014.Macon is served by three interstate highways: I-16 (connecting the city to Savannah and coastal Georgia), I-75 (connecting the city with Atlanta to the north and Valdosta to the south), and I-475 (a city bypass highway).
The city has several institutions of higher education, as well as numerous museums and tourism sites. The area is served by Middle Georgia Regional Airport and Herbert Smart Downtown Airport. The mayor is Lester Miller.
