Souliotes (Greek: Σουλιώτες, also spelled Souliots or Suliots) were a warlike community from the area of Souli, in Greece, who became famous across Greece for their resistance against the local Ottoman Pashalik of Yanina ruled by the Muslim Albanian Ali Pasha. After their defeat in 1803, the Souliotes were forced to move to the rest of Greece, and many of them played a prominent role in the Greek War of Independence starting in 1821, under leaders such as Markos Botsaris and Kitsos Tzavelas.

The Souliotes originally spoke their own sub-branch of the Cham Albanian dialect and eventually became bilingual in Greek and Albanian.After their assimilation, a language shift to Greek occurred, while the Souliotic dialect became extinct.
