Psachna (Greek: Ψαχνά) is a town in Euboea, central Greece, 16 km north of Chalcis.

The settlement of Psachna was built by refugees after the sack of Chalcis in 1470 during the First Ottoman–Venetian War.

The population of Psachna was increased in the last century when residents of the more mountainous villages such as Pyxaria, Vavoula, Apogremno moved in.
