The National Theatre of the Deaf (NTD) is a Connecticut-based theatre company founded in 1967, and is the oldest theatre company in the United States with a continuous history of domestic and international touring, as well as producing original works. NTD productions combine American Sign Language with spoken language to fulfill the theatre's mission statement of linking Deaf and hearing communities, providing more exposure to sign language, and educating the public about Deaf art. The NTD is affiliated with a drama school, also founded in 1967, and with the Little Theatre of the Deaf (LTD), established in 1968 to produce shows for a younger audience.
