Allatini Villa, Protected building in Ntepo, Thessaloniki, Greece.

Allatini Villa is a three-story baroque building on Vasilissis Olgas Avenue in Thessaloniki. It features richly decorated facades and ornamental details designed by architect Vitaliano Poselli.

Villa Allatini was built in 1898 by Italian architect Vitaliano Poselli as a country residence for the Jewish Allatini family, when the area was the eastern edge of Ottoman Thessaloniki. From 1909 to 1911 it housed the deposed Sultan Abdul Hamid II under house arrest. In 1926 it held the Philosophical School of the new University of Thessaloniki, and during the Greco-Italian War of 1940–1941 it served as a hospital.

The villa displays Italian architectural influence that spread through Greece in the late 1800s. Its baroque decorations and facade elements show the European taste favored by wealthy families of that era.

The villa stands on Vasilissis Olgas Avenue in the Depot area, at the eastern end of Thessaloniki's centre. It now houses the few remaining offices of the Region of Central Macedonia, so the interior is not open to visitors. The three-storey facade can be seen and photographed from the avenue.

The same architect, Vitaliano Poselli, designed both the villa and the Allatini Mills, which opened in 1890, eight years before the house. The area around it was then called the district of "Countrysides" or "Towers" and marked the eastern edge of Thessaloniki.
