Vyronas (Greek, Modern: Βύρωνας, Ancient/Katharevousa: Βύρων - Vyron ) is a suburb in the northeastern part of Athens, Greece. The city is named after George Gordon Byron, 6th Baron Byron, the famous English poet and writer, who is a national hero of Greece. It is located south of Attiki Odos (number 65), also known as the Hymettus Ring, which opened in 2004 with the Katechaki interchange. It is also located southeast of Athens and east and northeast of Vouliagmenis Avenue.
Vyronas started as a commune and later became a municipality.
The area was made up of farmlands to the west and the rocky areas of the Hymettus to its east ; urban development replaced much farmland in the 1920s and the 1930s. Today, the area from the western to the east-central part of the municipality is urbanized, while the businesses are within its main avenues and streets. The forest of Hymettus lies to the east.
Vyronas has schools, lyceums, gymnasia, banks, two post offices and squares (plateies).
