The American Theatre Critics Association (ATCA) is a national association of professional theatre critics whose members include critics for newspapers, magazines, radio, television, and online outlets.

In 1974, a group of theatre critics who had been gathering at the O'Neill Theatre Center in Waterford, Connecticut decided that there was a need for a national organization of theatre critics, especially with the expansion of professional regional theatre. They founded ATCA to provide theatre critics in cities with smaller theatre communities with opportunities and resources as well as training. They also wanted to advocate for freedom of creative expression in theatre and theatre criticism. ATCA holds a four day annual conference in New York and hosts panels, workshops, seminars, and other opportunities for theatre critics to meet and discuss regional theater. As of 2018, ATCA is still active.
