Cobb County is in the U.S. state of Georgia, and is a core county of the Atlanta metropolitan area in the north-central portion of the state. As of the 2020 Census, the population was 766,149. It is the state's third most populous county, after Fulton and Gwinnett counties. Its county seat is Marietta; its largest city is Mableton.
Along with several adjoining counties, Cobb County was established on December 3, 1832, by the Georgia General Assembly from the large Cherokee County territory—land northwest of the Chattahoochee River which the state acquired from the Cherokee Nation and redistributed to settlers via lottery, following the passage of the federal Indian Removal Act. The county was named for Thomas Willis Cobb, a U.S. representative and senator from Georgia. It is believed that Marietta was named for his wife, Mary. Cobb County is included in the Atlanta metropolitan area and is situated immediately to the northwest of Atlanta's city limits. Its Cumberland District, an edge city, has over 24 million square feet (2,200,000 m) of office space. Major League Baseball's Atlanta Braves have played home games at Truist Park in Cumberland since 2017.
