North Shore Music Theatre is the largest operating regional theater in New England. It is located in Beverly, Massachusetts and is one of the few remaining theatre-in-the-round stages left in the United States. The theater is owned by Massachusetts businessman Bill Hanney.

North Shore Music Theatre (NSMT) was organized in 1954 by founders Stephan Slane and Ruby Newman. The theater "opened as a partstar-centered comedies". After route 128 was finished in the 1960s, permanent walls were constructed along with heating and air conditioning, and the capacity of the theater was increased from 1,000 to 1,750 and later 1,800 seats. The theater became the largest non-profit theater in New England, and up to 350,000 people attended the musicals performed each year. The theatre annually presented a series of celebrity concerts of children's musicals. It also housed the Youth Performance Academy that provided an opportunity for child actors to perform. The theater produced the world premiere of the Tony Award-winning musical Memphis in 2003, as well as the regional premieres of Hairspray, Thoroughly Modern Millie, Ragtime, and many others.[citation needed]
