The League of Resident Theatres, the association of the country's major nonprofit professional theaters.
LORT is a group of around seventy-five of the largest nonprofit professional theaters in the United States. Membership matters mostly to the people who work there, because it sets the union contracts, but for audiences "a LORT theater" is a reliable shorthand for a well-established professional regional company.
