The American Choral Directors Association (ACDA), headquartered in Oklahoma City, Oklahoma, is a non-profit organization with the stated purpose of promoting excellence in the field of choral music. Its membership comprises approximately 22,000 choral directors representing over a million singers.^[1]

ACDA is organized in six regions: Midwestern, Eastern, Northwestern, Southern, Southwestern, and Western. Every year, conferences with topics pertaining to choral conductors are held. In even numbered years, a region conference is held in each region, and in odd numbered years, a national conference takes place in a major U.S. city. In 2021, ACDA organized its first virtual national conference in response to the COVID-19 pandemic. In 2023, the organization returned to an in person conference, with Cincinnati serving as the host city. Each year, a different university hosts the yearly ACDA chapter.^{[citation needed]}

Their official publications are the Choral Journal, as well as the scientific research journal International Journal of Research in Choral Singing (online only).^{[citation needed]}

Robyn Hilger is the current executive director.^[2]

Since 1991, the ACDA awards the "Raymond W. Brock Memorial Commission" to "a recognized composer to write a choral composition in an effort to perpetuate quality choral repertoire."^[3]
