Thomas Moore, also known as Tom Moore, was an Irish writer, poet, and lyricist celebrated for his Irish Melodies. His setting of English-language verse to old Irish tunes marked the transition in popular Irish culture from Irish to English. Politically, Moore was recognised in England as a press, or "squib", writer for the aristocratic Whigs; in Ireland he was accounted a Catholic patriot.

"The Last Rose of Summer" is a poem by the Irish poet Thomas Moore. He wrote it in 1805, while staying at Jenkinstown Castle in County Kilkenny, Ireland, where he was said to have been inspired by a specimen of Rosa 'Old Blush'.
