The Shapsug (шапсыгъ ʃaːpsəʁ, шапсуги, Şapsığlar, الشابسوغ, שפסוגים) (also known as the Shapsugh or Shapsogh) are one of the twelve major Circassian tribes. Historically, the Shapsug tribe comprised one of the largest groups of the Black Sea Adyghe (Причерноморские адыги). They inhabited the region between the Dzhubga (in Жьыбгъэ means "Winds" or "The Valley of Winds") River and the Shakhe Rivers (the so-called Maly Shapsug, or Little Shapsug) and high-altitude mountainous areas of the northern slopes of the Caucasus range along the Antkhir, Abin, Afips, Bakan, Ships, and other rivers (Bolshoy Shapsug, or Greater Shapsug).
In Russia, the remaining Shapsug population mainly live in the Tuapsinsky District (Tuapse) of Krasnodar Krai, Lazarevsky City District of Sochi, and in the Republic of Adygea (mainly in District of Takhtamukaysky and District of Teuchezksky), which were a small part of historical Circassia.
However, today the major Shapsug communities are found in Turkey, Israel (Kfar Kama), Jordan (Amman, Na'our, Marj Al-Hamam, Wadi Al-Seer), Lebanon (Tripoli, Berkayel -Akkar), Iraq, Syria, Western Europe, and the United States of America. The first Circassians to settle in Amman were from the Shapsug tribe, and as a result the Shapsug's neighbourhood is considered the oldest neighbourhood in the Capital Amman and was the down town of it; however, other Circassians from the Kabardian, Abadzekh, and Bzhedug tribes also settled in Amman afterwards. Today, the Shapsug are the third-most numerous Circassian tribe in the world, after the most numerous Kabardian and second-most numerous Abzakh tribes. The Shapsug are the most numerous Circassian tribe in Israel, third-most numerous in Turkey where the majority of them live, and the fifth-most numerous one in Russia. In Jordan, after the Abzakh, the Shapsug and Kabardian tribes are the most numerous Adyghe tribes.
The Shapsug speak a sub-dialect of the Adyghe language.
