Nea Vyssa (Greek: Νέα Βύσσα) is a village in the northeastern part of the Evros regional unit in Greece.

After the Greco-Turkish War (1919-1922) Greek refugees from the village Vyssa (now Bosna, 4 km to the north in Turkey) settled in Achyrochori.

In 1971, OSE, in a bid to avoid using the Edirne curve, built a cut off line just north of the village.

Today, trains still call at Ormenio, and other stations to the north of Nea Vyssa, but no long use Karaağaç, which has since closed.

The village is served by the station Vyssa on the Alexandroupoli–Svilengrad Line, with services to Alexandroupoli and Ormenio.
