Irish folklore () refers to the folktales, balladry, music, dance and mythology of Ireland. It is the study and appreciation of how people lived.

The folklore of Ireland includes banshees, fairies, leprechauns and other mythological creatures, and was typically shared orally by people gathering around, sharing stories. Many tales and legends were passed from generation to generation, so were the dances and song in the observing of important occasions such as weddings, wakes, holidays, etc.

Definition

What constitutes Irish folklore may be rather fuzzy<!--"nebulous"--> to those unfamiliar with Irish literature. Diarmuid Ó Giolláin, for one, declared that folklore was elusive to define clearly.<!--"Folklore escapes clear definition"-->

Bo Almqvist (c. 1977) gave an all-encompassing definition that folklore covered "the totality of folk culture, spiritual and material", and included anything mentioned in Seán Ó Súilleabháin's A Handbook of Irish Folklore (1942).<!--although Almqvist gave 1940 date-->

Handcraft and herb lore

Also part of Irish folklore are the handed-down skills, such as basket-weaving or making Brigid's crosses.

As an example, shallow wicker baskets called skeeoges as strainers (to empty the boiled potatoes and hot water on, to drain the liquid) were recorded in the Co. Wexford area by Patrick Kennedy in the 19th century. A later folklore collector was unable to ascertain whether this practice was carried out in the locality during the field work in the 1950s (or in the revisit in 1970's). This basket's name skeeoge supposedly derived from the Gaelic word for "shield" ().

The Irish Folklore Commission has accumulated a collection of crosses made on St. Bridget's Day (1 February), and various craft objects made of plaited straw, etc., gathered from across the county.

The race of fairy people () were thought to be descendants of the Tuatha Dé Danann, a godlike race who came to Ireland and conquered the people there. They are described as human sized, beautiful, powerful, and in tune with nature, similar to the modern day fantasy race of Elves.alt=Two green "fairy" trees next to each other in a lush pasture.|thumb|Fairy Trees near Greenan. According to fairy lore, the hawthorn tree, also known as a fairy tree, is said to mark the territory of the fairies.

Instead of living together like the elite fairy race, solitary fairies are secretive and isolated, often staying away from humans and coming out at night. The solitary fairies include a wide range of magical creatures in Irish folklore.

One type of Irish fairy is the female banshee, the death-messenger with her keening, or baleful crying over someone's death, and known by many different names.

Another well-recognized Irish fairy is the leprechaun, which many have identified as the maker of shoes.
