Ayran is a cold yogurt beverage mixed with salt. In addition to Turkey, where it is considered a national drink, ayran can be found in neighboring nations and regions including Azerbaijan, Bulgaria, Iran, and Arab countries.

Its primary ingredients are water and yogurt, and ayran has been variously described as "diluted yogurt" and "a most refreshing drink made by mixing yogurt with iced water".
