Théâtre du Nouvel-Ontario

Théâtre du Nouvel-Ontario (Theatre of New-Ontario) is a Canadian professional theatre company. Located in Sudbury, Ontario, the company produces French language stage productions.

The company was founded in 1971 by the Coopérative des artistes du Nouvel-Ontario, a group of artists that included André Paiement, Marcel Aymar, Denis St-Jules and Robert Paquette. It evolved out of an informal association of students at Laurentian University who united to write and perform a Franco-Ontarian musical theatre show, Moé, j'viens du nord, 'stie!, in 1970.

Other artists later to be associated with the company included Jean-Marc Dalpé and Brigitte Haentjens.

The company originally staged theatre productions at Laurentian's Fraser Auditorium. It subsequently acquired a former bakery on King Street in the city's Flour Mill neighbourhood, and remained there until building a new theatre on the grounds of Collège Boréal in the late 1990s. It is slated to move in 2022 to the new Place des Arts facility in downtown Sudbury.
