There are four Turkic-speaking populations native to Ukraine. 

Three of them are native to Crimea. The Crimean Tatars being traditionally Muslims. Krymchaks were traditionally Rabbinic Jews. The Karaites on the other hand identified as Karaite Jews, however historical consequences lead the Karaites of Ukraine and Poland to identify themselves as distinct from the Jews of Eastern Europe and West Asia. Under the rule of the Russian Czar this lead them to have the same rights as Christians and Muslims of the area. Later after the Nazi invasion of the Soviet Union this assertion lead to the Nazis identifying them as non-Jewish as well, thus preventing them from meeting the same fate as Krymchaks who were nearly obliterated as a people. Despite this genetic studies have shown that they have a similar origins with other European and Levantine Jews, and are genetic isolates alongside their Krymchak neighbors in comparison to their Muslim and Christian neighbors. 

The Gagauz are native the Bessarabia. They are unique among Turkic-speaking populations, alongside certain Volga Turkic populations in Russia, in that they converted to Eastern Orthodoxy in the Middle Ages.
