Cinnamon is a spice obtained from the inner bark of several trees from the genus Cinnamomum that is used in both sweet and savoury foods. The term "cinnamon" also refers to its mid-brown colour.

Cinnamon bark is used as a spice. It is principally employed in cookery as a condiment and flavouring material. It is used in the preparation of chocolate, especially in Mexico, which is the main importer of cinnamon.

 It is also used in many dessert recipes, such as apple pie, doughnuts, and cinnamon buns, as well as spicy candies, coffee, tea, hot cocoa, and liqueurs.

In the Middle East, cinnamon is often used in savoury dishes of chicken and lamb.

In the United States, cinnamon and sugar are often used to flavour cereals, bread-based dishes, such as toast, and fruits, especially apples; a cinnamon-sugar mixture is even sold separately for such purposes.

It is also used in Turkish cuisine for both sweet and savoury dishes. Cinnamon can also be used in pickling.

Cinnamon powder has long been an important spice in enhancing the flavour of Persian cuisine, used in a variety of thick soups, drinks, and sweets
