Cham Albanians or Chams (Albanian: Çamë; Greek: Τσάμηδες, Tsámidhes), are a sub-group of Albanians who originally resided in the western part of the region of Epirus in northwestern Greece, an area known among Albanians as Chameria. The Chams have their own particular cultural identity, which is a mixture of Albanian and Greek influences as well as many specifically Cham elements. A number of Chams contributed to the Albanian national identity and played an important role in starting the renaissance of the Albanian culture in the 19th century. The Chams speak their own dialect of the Albanian language, the Cham Albanian dialect, which is a Southern Tosk Albanian dialect and one of the two most conservative ones; the other being Arvanitika.

During the late 1930s Chams suffered from intimidation and persecution under the dictatorship of General Metaxas. Following the Italian occupation of Albania in 1939, the Chams became a prominent propaganda tool for the Italians and irredentist elements among them became more vocal. As a result, on the eve of the Greco-Italian War, Greek authorities deported the adult male Cham population to internment camps. After the occupation of Greece, large parts of the Muslim Cham population collaborated with Italian and German forces. This fueled resentment among the local Greek population and in the aftermath of World War II the entire Muslim Cham population had to flee to Albania. Most Chams settled in Albania, while others formed émigré communities in Turkey and the United States, and today their descendants continue to live in these countries. Since the fall of Communism in Albania, Chams in Albania have campaigned for right of return to Greece and restoration of confiscated properties. According to Laurie Hart, the remaining Orthodox Cham communities in Epirus are nowadays assimilated and entirely identify with the Greek nation. On the other hand, Bugajski includes the Orthodox among Cham Albanians. While in Albania and the diaspora Chams have preserved their dialect, traditions and folk songs, in Greece the Orthodox Chams have suffered from assimilation and the public suppression of their Albanian heritage and language. As a result, Albanian is only spoken privately at their homes.
