The Municipal Gallery of Athens is a museum in Athens, Greece. It houses a rich collection of nearly 3,000 works from leading 19th- and 20th-century Greek artists. Formerly located on Peiraios Street on Eleftherias (Koumoundourou) Square, in October 2010 the gallery moved three blocks northwest to the corner of Myllerou and Leonidou streets on Avdi Square in Metaxourgeio.
