The theatre is named after the play
Théâtre de Neptune, which was performed at
Port Royal, Nova Scotia as the first theatrical production in North America. The Neptune was opened on the site of a former cinema in 1963 during Canada's drive to create regional theatres. Its first artistic director was
Leon Major. His vision was a year-round touring repertory company modelled on the
Moscow Art Theatre. Play selection would be a mix of classical drama, contemporary international theatre, and new Canadian plays, similar to the
Crest Theatre that Major had directed at numerous times before. Its first President of the Board was local surgeon and CBC writer Dr. Arthur L. Murphy. Its first production was
Major Barbara by George Bernard Shaw. The building was renovated in 1997 and now has two theatres and incorporates a theatre school. ==Artistic directors==
