The Last Rose of Summer is a poem by Irish poet Thomas Moore written in 1805 in County Kilkenny, Ireland. It is set to a traditional tune called Aislean an Oigfear or The Young Man's Dream, which had been transcribed by Edward Bunting in 1792 based on a performance by harper Donnchadh Ó hÁmsaigh (Denis Hempson) at the Belfast Harp Festival. There are innumerable arrangements of as well the tune as the poem during the 19th century. One of those is the setting of Friedrich von Flotow which he included as Letzte Rose in the opera Martha and became very popular on its own.
