Merrimack Repertory Theatre has been Merrimack Valley’s professional theatre company since 1979, and is an integral part of Lowell’s identity as the cultural heart of the region. Merrimack Repertory Theatre's mission is to share theatrical stories of human understanding that reflect and engage our community. MRT is a cultural resource for its community and strives to remove barriers to access and build community partnerships. MRT produces a seven-show season of new plays from September through May in our 279-seat theatre, the Nancy L. Donahue Theatre in Liberty Hall.
