The Gagauz people are a Turkic group living mostly in southern Moldova (Gagauzia), southwestern Ukraine (Budjak), south-eastern Romania (Dobrogea), northeastern Bulgaria, Greece, Brazil, America and Canada. Unlike most other Turkic speaking people, the Gagauz are predominantly Orthodox Christians. There is a related ethnic group also called Gagavuz (or Gajal) living in the European part of northwestern Turkey.

Today Gagauz people outside Moldova live mainly in the Ukrainian regions of Odesa and Zaporizhia, as well as in Kazakhstan, Kyrgyzstan, Uzbekistan, Bulgaria, Romania, Brazil, Turkmenistan, Belarus, Estonia, Latvia, Georgia, Turkey and the Russian region of Kabardino-Balkaria.

There are also nearly 20,000 descendants of Gagauzes living in the Balkan country of Bulgaria, as well as upwards of 2,000 living in the United States of America, Brazil and Canada. Most of Gagauz immigrants in the USA are Evangelical Christians, who left their homeland in Moldova as refugees. They were persecuted by the communist government of the Soviet Union. Gagauz immigrants live in Sacramento, California; Salem, Oregon; Seattle, Washington; Broken Arrow, Oklahoma; Tacoma, Washington; Charlotte, North Carolina; Philadelphia, Pennsylvania; and in Massachusetts. The official figures in the latter group of countries cited in this article are much lower due to the loss of Gagauz identity during the last century.

The Turkic peoples are a collection of ethnic groups that live in northern, central and western Asia, northwestern China and parts of eastern Europe. They speak languages belonging to the Turkic language family. They share, to varying degrees, certain cultural traits and historical backgrounds. The term Turkic represents a broad ethno-linguistic group of people including existing societies such as the Turkish, Azerbaijani, Chuvashes, Kazakhs, Tatars, Kyrgyzs, Turkmens, Uyghurs, Uzbeks, Bashkirs, Qashqai, Gagauzs, Yakuts, Crimean Karaites, Krymchaks, Karakalpaks, Karachays, Nogais and as well as past civilizations such as the Göktürks, Kumans, Kipchaks, Avars, Bulgars, Turgeshes, Khazars, Seljuk Turks, Ottoman Turks, Mamluks, Timurids and possibly Huns and the Xiongnu.

The distribution of people of Turkic cultural background ranges from Siberia, across Central Asia, to Eastern Europe. As of 2011^[update] the largest groups of Turkic people live throughout Central Asia—Kazakhstan, Kyrgyzstan, Turkmenistan, Uzbekistan, and Azerbaijan, in addition to Turkey and Iran. Additionally, Turkic people are found within Crimea, East Turkistan region of western China, northern Iraq, Pakistan, Israel, Russia, Afghanistan, and the Balkans: Moldova, Bulgaria, Romania, and former Yugoslavia. A small number of Turkic people also live in Vilnius, the capital of Lithuania. Small numbers inhabit eastern Poland and the south-eastern part of Finland. There are also considerable populations of Turkic people (originating mostly from Turkey) in Germany, United States, and Australia, largely because of migrations during the 20th century.
