The Louisville Bats are a Minor League Baseball team of the International League (IL) and the Triple-A affiliate of the Cincinnati Reds. They are located in Louisville, Kentucky, and are named in dual reference to the winged mammal and baseball bats, such as those manufactured locally under the Louisville Slugger brand. The team plays their home games at Louisville Slugger Field, which opened in 2000. The Bats previously played at Cardinal Stadium from 1982 to 1999.

Triple-A has been the highest level of play in Minor League Baseball in the United States since 1946. Currently, two leagues operate at the Triple-A level, the International League (IL) and the Pacific Coast League (PCL). There are 30 teams, one per each Major League Baseball (MLB) franchise, with 20 in the IL and 10 in the PCL. Triple-A teams are generally located in smaller cities as well as larger metropolitan areas without MLB teams, such as Austin, Jacksonville, Columbus, and Indianapolis. Four Triple-A teams play in the same metro areas as their parent clubs.
