The Hayes Theatre is a 111-seat theatre specialising in music theatre and cabaret in Potts Point, Sydney, Australia. It is named after the Australian performer Nancye Hayes. Hayes Theatre Co was established at the former Darlinghurst Theatre after the Darlinghurst Theatre Company moved to the nearby Eternity Playhouse. Its first production, a revival of Sweet Charity, opened in January 2014. The production transferred to the Sydney Opera House and a national tour, and was nominated for and received multiple Helpmann Awards.
