The Athens Concert Hall (Greek: Μέγαρον Μουσικής Αθηνών, Mégaron Mousikis Athinon) is a concert hall located on Vasilissis Sofias Avenue in Athens, Greece.

The Hall was inaugurated in 1991 with two halls. Since then it has been augmented with two more halls and now has a total of four: two large and two smaller ones. The Hall has optimal facilities for opera performances, and some operas are presented every season.

The Megaro Moussikis station of the Athens Metro is just outside the Hall, on Line 3.

The design of the 8,000 square meters floor was performed by Christopher Alexander; the process of designing and laying the floor and its result are described in his work The Nature of Order: An Essay on the Art of Building and the Nature of the Universe.^[1]
