Corner Theatre E.T.C. (Corner Theatre) was an American experimental theater in operation from 1968–1987, a not-for-profit cultural organization located in Baltimore, Maryland, which provided resources for new playwrights, designers, directors, actors, dancers, and other artists seeking alternative means and avenues for self-expression, and social and political commentary. Throughout most of its nineteen-year existence, Corner Theatre ETC remained dedicated to the presentation of original plays, while encouraging a confrontational approach to production.
