New York State Theatre Institute (NYSTI) was a New York State public-benefit corporation that organized theatre education programs for young people in New York State. Its forerunner was created by statute in 1974. The Institute produced over 30 plays and musicals for family and school audiences, and provided a theatre-arts school, summer programs, and internships. The company toured within New York State and abroad. The Institute closed in 2010 following a State enquiry into alleged irregularities.
