The suburb was named after Ionia, the region in Anatolia from which many Greeks came in the 1920s after the Asia Minor Disaster. Originally, the area was named "Podarades" and was made up of farmlands and forests. However, the refugees quickly developed it into a thriving community with businesses. In 1934 it became a municipality. In 1956 Nea Ionia acquired a train station on the Athens to Piraeus line (ISAP). Today, much of the municipality is urbanized while the businesses are along its main roads.
Nea Ionia has been the home of several celebrities including:
- Singer Stelios Kazantzidis
- Singer Maria Farandouri
- Actor Nikos Xanthopoulos
- Singer Yiota Lydia
- Footballer Stelios Skevofilakas
- Footballer/coach Yiannis Pathiakakis
Nea Ionia has schools, lyceums, gymnasia, banks, a post office and squares (plateies).
