Dionysos, Dionyssos, Dionissos or Dionissos (Greek: Διόνυσος) is a rather exclusive suburb in northeastern Attica, Greece -- just about 23 km northeast of Athens.

Another series of mountains and forests lie to the north. Much of the municipality are forested. Dionyssos since the mid to late 1980s is connected with the urban sprawl of Athens but it is east of the agglomeration of Athens as well as the Megali Daktylo. The residential area covers the western part of the municipality. Dionyssos is passed by a road linking to the mountains and to Nea Makri. Dionyssos is accessed with an interchange with GR-1/E75 (Athens - Lamia - Thessaloniki) at the 19th km 8 km NE and at the 21st km near Varympompi 8 km SE and GR-83 whic is also known as Theseos (Theseus) Avenue to the west. The Athenian plain lies to the west. Dionyssos is located SE of Thiva, S of Euboea and Oropos, SW of Marathon, NE of Kifissia and NE of the Attiki Odos (number 6).
Until the 1980s and the 1990s, farmlands cover the northwestern part and the slopes of Dionyssos which existed into the 1990s and were mainly luxury homes.
