Iranian cuisine comprises the cooking traditions of Iran. The term Persian cuisine is used as well due to the fact that Iran is historically known as Persia in the West, even though ethnic Persians are only one of Iran's native ethnic groups that have contributed to the culinary culture.

Iran's culinary culture has historically interacted with the cuisines of the neighboring regions, including Caucasian cuisine, Turkish cuisine, Levantine cuisine, Greek cuisine, Mesopotamian cuisine, Central Asian cuisine, and Russian cuisine. Through the various Persianized Muslim sultanates and the Central Asian Mughal dynasty, aspects of Iranian cuisine were also adopted into Indian and Pakistani cuisines.

Typical Iranian main dishes are combinations of rice with meat, vegetables, and nuts. Herbs are frequently used, along with fruits such as plums, pomegranates, quince, prunes, apricots, and raisins. Characteristic Iranian flavorings such as saffron, dried lime and other sources of sour flavoring, cinnamon, turmeric, and parsley are mixed and used in various dishes.

Outside Iran, Persian food is especially found in cities of the Iranian diaspora such as London, the San Francisco Bay Area, and Toronto, Houston and especially Los Angeles and its environs.

Historical Iranian cookbooks

Although the Arabic cookbooks written under the rule of the Abbasid Caliphate—one of the Arab caliphates which ruled Iran after the Muslim invasion—include some recipes with Iranian names, the earliest surviving classical cookbooks in Persian are two volumes from the Safavid period. The older one is entitled "Manual on cooking and its craft" (Kār-nāmeh dar bāb e tabbāxī va sanat e ān) written in 927/1521 for an aristocratic patron at the end of the reign of Ismail I. The book originally contained 26 chapters, listed by the author in his introduction, but chapters 23 through 26 are missing from the surviving manuscript. The recipes include measurements for ingredients—often detailed directions for the preparation of dishes, including the types of utensils and pots to be used—and instructions for decorating and serving them. In general, the ingredients and their combinations in various recipes do not differ significantly from those in use today. The large quantities specified, as well as the generous use of such luxury ingredients as saffron, suggest that these dishes were prepared for large aristocratic households, even though in his introduction, the author claimed to have written it "for the benefit of the nobility, as well as the public."

The second surviving Safavid cookbook, entitled "The substance of life, a treatise on the art of cooking" (Māddat al-ḥayāt, resāla dar ʿelm e ṭabbāxī), was written about 76 years later by a chef for Abbas I. The introduction of that book includes elaborate praise of God, the prophets, the imams, and the shah, as well as a definition of a master chef. It is followed by six chapters on the preparation of various dishes: four on rice dishes, one on qalya, and one on āsh. The measurements and directions are not as detailed as in the earlier book. The information provided is about dishes prepared at the royal court, including references to a few that had been created or improved by the shahs themselves. Other contemporary cooks and their specialties are also mentioned.
