Tandoori chicken is a dish made from chicken marinated in yogurt and spices and roasted in a tandoor, a cylindrical clay oven. The dish is now popular worldwide. The modern form of the dish was popularized by the Moti Mahal restaurant in New Delhi, India in the late 1940s.

A tandoor is a large vase-shaped oven, usually made of clay. Since antiquity, tandoors have been used to bake unleavened flatbreads, such as roti and naan, as well as to roast meat. The tandoor is predominantly used in Western Asian, Central Asian, South Asian, and Horn of African cuisines.
