Aliveri (Greek: Αλιβέρι) is a town and a community in the island of Evvoia, Greece.

Aliveri is situated in the central part of the island, on the South Euboean Gulf.

The Greek National Road 44 (Thebes - Chalcis - Karystos) passes through the town.

The biggest cement factory of Greece and a power generating plant of the Public Power Corporation (ΔΕΗ) are located in Aliveri.

As the lignite seam has been exhausted now, the power plant is using oil.
