The Atlanta Crackers were a Minor League Baseball team based in Atlanta, Georgia, between 1901 and 1965. The Crackers were Atlanta's home team until the Atlanta Braves moved from Milwaukee, Wisconsin, in 1966.

Atlanta played its inaugural Southern Association game, against the Nashville Baseball Club, on Saturday, April 26, 1902 (Memorial Day) in Piedmont Park before a crowd of around 3,500. For 60 years (until 1961), the Crackers were part of the Class AA Southern Association, a period during which they won more games than any other Association team, earning the nickname the "Yankees of the Minors". In 1962, the Association disbanded. Then, the former Miami Marlins, a Class AAA International League team that had spent 1961 playing in San Juan, Puerto Rico, and Charleston, West Virginia, moved to Atlanta and adopted the Crackers name, from "Georgia cracker" (which refers to early white settlers in Georgia) and "cracker," a pejorative term for poor rural White Southerners.

Originally the top affiliate of the St. Louis Cardinals, the AAA Crackers spent the 1964 season as the Minnesota Twins' top affiliate. Then, in 1965, the Milwaukee Braves became the Crackers' parent club. That team had bought the Crackers as part of their planned move to Atlanta in 1965; under MLB rules of the day, ownership of a minor league team also carried the major league rights to that city. However, an injunction forced the Braves to play a lame-duck season in Milwaukee. The Braves finally moved to Atlanta in 1966, and moved the Crackers to Richmond, Virginia, as the Richmond Braves. In a return home of sorts, the team moved to Gwinnett County, a northeastern suburb of Atlanta, in 2009 as the Gwinnett Braves, now the Gwinnett Stripers. Dating back to their time as the Crackers, the Stripers have been the Braves' top affiliate for 57 seasons, the longest-running affiliation agreement in Triple-A.

The Crackers won the Dixie Series, a postseason interleague championship between the champions of the Southern Association and the Texas League, in 1938 and 1954.

The Crackers played in Ponce de Leon Park from 1907 until a fire on September 9, 1923, destroyed the all-wood stadium. Spiller Field (a stadium later also called Ponce de Leon Park), became their home starting in the 1924 season; it was named in honor of a wealthy businessman who paid for the new concrete-and-steel stadium. That new park was unusual because it was constructed around a magnolia tree that became part of center field. Balls landing in the tree remained in play, until Earl Mann took over the team in 1947 and had the outfield wall moved in about fifty feet. The Crackers played their last season in the newly built Atlanta Stadium (later known as Atlanta–Fulton County Stadium) in 1965.

The Crackers were independent of major league farm systems until 1950. They then became a AA affiliate of the Boston/Milwaukee Braves (1950–1958) and Los Angeles Dodgers (1959–1961) during the last decade of the Southern Association's existence. As an International League team, they were the top affiliate of the St. Louis Cardinals (1962–63), Minnesota Twins (1964) and the Braves again (1965).

According to Tim Darnell, who wrote The Crackers: Early Days of Atlanta Baseball, the origins of the team name is unknown.

Darnell cites several possibilities as to why this name was chosen:
