The Celtic Revival is a variety of movements and trends in the 19th, 20th and 21st centuries that see a renewed interest in aspects of Celtic culture. Artists and writers drew on the traditions of Gaelic literature, Welsh-language literature, and Celtic art—what historians call insular art. Although the revival was complex and multifaceted, occurring across many fields and in various countries in Northwest Europe, its best known incarnation is probably the Irish Literary Revival. Irish writers including William Butler Yeats, Lady Gregory, "Æ" Russell, Edward Martyn, Alice Milligan and Edward Plunkett stimulated a new appreciation of traditional Irish literature and Irish poetry in the late 19th and early 20th century.

Celtic art is associated with the peoples known as Celts; those who spoke the Celtic languages in Europe from pre-history through to the modern period, as well as the art of ancient peoples whose language is uncertain, but have cultural and stylistic similarities with speakers of Celtic languages.
