Irish cuisine is a style of cooking originating from Ireland or developed by Irish people. It evolved from centuries of social and political change. The cuisine takes its influence from the crops grown and animals farmed in its temperate climate. The introduction of the potato in the second half of the 16th century heavily influenced Ireland's cuisine thereafter. Representative Irish dishes are Irish stew, bacon and cabbage, potato, boxty, coddle, colcannon and (mainly in Ulster) fadge.

There are many references to food and drink in Irish mythology and early Irish literature such as the tale of Fionn mac Cumhaill and the Salmon of Knowledge The old stories also contain many references to banquets, although these may well be greatly exaggerated and provide little insight into everyday diets. Honey seems to have been widely eaten and used in the making of mead. There are also many references to fulacht fiadh, which may have been sites for cooking deer, consisting of holes in the ground which were filled with water. The meat was placed in the water and cooked by the introduction of hot stones. Many fulacht fiadh sites have been identified across the island of Ireland, and some of them appear to have been in use up to the 17th century.
