The National Theatre of Northern Greece or NTNG (Greek: Κρατικό Θέατρο Βορείου Ελλάδος, ΚΘΒΕ) is an institution promoting performing arts primarily in Thessaloniki and Northern Greece, founded in 1961.

[1] NTNG was founded in 1961.The same year Sokratis Karantinos was appointed its first director and Yiorgos Theotokas its first president.

[2][3] Royal Theatre was the initial base of the institution but shortly after NTNG moved its headquarters to the complex of the Society of Macedonian Studies.

[4][5] Megaron B', which hosts the theatre, was designed in early 1951 by Vasilis Kassandras,[6] influenced by the Théâtre des Champs-Élysées.

Its activity is not limited to theatrical productions but extends to cultural sectors such as education, literature and the arts through the organization of exhibitions, conferences, festivals, theatre-educational programmes[19] and so forth.
