Off-Off-Broadway theatrical productions in New York City are those in theatres that are smaller than Broadway and Off-Broadway theatres. Off-Off-Broadway theatres are usually theatres that have fewer than 100 seats, though the term can be used for any show in the New York City area that employs union actors but is not under an Off-Broadway, Broadway, or League of Resident Theatres contract. It is often used as a term relating to any show with non-union actors. The shows range from professional productions by established artists to small amateur performances.
