Marietta, city, seat (1834) of Cobb county, northwestern Georgia, U.S. It lies about 20 miles (30 km) northwest of Atlanta, in the Blue Ridge foothills. A settlement is thought to have existed on the site in the 1820s. The town was probably named for the wife of prominent jurist and legislator Thomas W. Cobb. Its growth was stimulated in the 1840s by the arrival of the Western and Atlantic Railroad.

During the American Civil War a major battle was fought at Kennesaw Mountain (June 27, 1864), just west of Marietta. The city was subsequently occupied by Union troops, who burned the city as they departed in November. Kennesaw Mountain National Battlefield Park, established in 1917 and occupying 4.5 square miles (11.7 square km), preserves the site, and thousands of soldiers are buried in the Marietta National and Confederate cemeteries.

The city’s industrial development was boosted in 1942 with the opening of a B-29 bomber plant (reactivated in 1951 by Lockheed Aircraft Corporation for jet aircraft production). The city is the seat of Kennesaw State University (1963) and Southern Polytechnic State University (1948). Dobbins Air Reserve Base is adjacent to the Lockheed Martin plant. Inc. village, 1834; city, 1852. Pop. (2000) 58,748; Atlanta–Sandy Springs–Marietta Metro Area, 4,247,981; (2010) 56,579; Atlanta–Sandy Springs–Marietta Metro Area, 5,268,860.
