Gramos (Greek: Γράμος, Aromanian: Gramosta) is a remote mountain village and a former municipality in Kastoria regional unit, Macedonia, Greece.

The village is a traditional Aromanian (Vlach) settlement, named after the nearby Gramos mountains to its south.

It had the smallest population of any municipality in Greece at 28 inhabitants in the 2001 Greek census.

A small road connects Gramos with Nestorio, 20 km to its east.

[4] The development of the economy of Gramos led to the overpopulation of herds and people in the late 18th and early 19th centuries.
