The culture of Ireland includes language, literature, music, art, folklore, cuisine, and sport associated with Ireland and the Irish people. For most of its recorded history, Irish culture has been primarily Gaelic. It has also been influenced by Anglo-Norman, English and Scottish culture. The Anglo-Normans invaded Ireland in the 12th century, and the 16th/17th century conquest and colonisation of Ireland saw the emergence of Tudor English culture repurposed in an Irish style. The Plantation of Ulster also introduced Scottish elements mostly confined to Northern Ireland.

It is unclear whether a form of Early Irish astrology existed prior to contact with Western astrology, as the earliest Irish language sources are simply translations from standard Western sources. Historian Peter Berresford Ellis argues that although there is evidence of the development of Irish astrology from the 7th Century AD onwards, anything earlier is left to conjecture based on continental Celtic artifacts like the Coligny calendar.

Gaelic Ireland was the Gaelic political and social order, and associated culture, that existed in Ireland from the prehistoric era until the early 17th century. Before the Norman invasion of 1169, Gaelic Ireland comprised the whole island. Thereafter, it comprised that part of the country not under foreign dominion at a given time, i.e. "The Pale". For most of its history, Gaelic Ireland was a "patchwork" hierarchy of territories ruled by a hierarchy of kings or chiefs, who were elected through tanistry. Warfare between these territories was common. Occasionally, a powerful ruler was acknowledged as High King of Ireland. Society was made up of clans and, like the rest of Europe, was structured hierarchically according to class. Throughout this period, the economy was mainly pastoral and money was generally not used. A Gaelic Irish style of dress, music, dance, sport, architecture, and art can be identified, with Irish art later merging with Anglo-Saxon styles to create Insular art.

A high cross or standing cross is a free-standing Christian cross made of stone and often richly decorated. There was a unique Early Medieval tradition in Ireland and Britain of raising large sculpted stone crosses, usually outdoors. These probably developed from earlier traditions using wood, perhaps with metalwork attachments, and earlier pagan Celtic memorial stones; the Pictish stones of Scotland may also have influenced the form. The earliest surviving examples seem to come from the territory of the Anglo-Saxon kingdom of Northumbria, which had been converted to Christianity by Irish missionaries; it remains unclear whether the form first developed in Ireland or Britain.

In Ireland, England, Wales, and the Scandinavian Peninsula, the skulls of horses have been found concealed in the structures of buildings, usually under the foundation or floor.

In the United Kingdom and some other parts of the Commonwealth, where it is not customary to have a public viewing ceremony before the funeral, the term is sometimes used for a gathering held after the funeral.
