American Choral Directors Association

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.

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.

Their official publications are the Choral Journal, as well as the scientific research journal International Journal of Research in Choral Singing (online only).

Robyn Hilger is the current executive director.
