The Hayes Theatre is a 111-seat theatre for small-scale music theatre and cabaret in the Potts Point area of Sydney, Australia. It is named after the Australian performer Nancye Hayes.
The Hayes Theatre 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.
It is home for the New Musicals Australia program to foster the development of writers and composers of new Australian musicals.
