"The Lass of Richmond Hill", also known as "The Sweet Lass of Richmond Hill", is a song written by Leonard McNally with music composed by James Hook, and was first publicly performed in 1789. It was said to be a favourite of George III and, at one time, was thought to have been written by his son, George IV. It is a love ballad which popularized the poetic phrase "a rose without a thorn" as a romantic metaphor. Associated with the English town of Richmond in North Yorkshire, it is now often mistakenly considered to be a traditional folk song, and has been assigned the number 1246 on the Roud Folk Song Index. The music is also used as a military march by the British army.
