The Belfast Harp Festival, called by contemporary writers The Belfast Harpers Assembly, 11–14 July 1792, was a three-day musical and patriotic event organised in Belfast, Ireland, by leading members of the local Society for Promoting Knowledge (the Linen Hall Library): Dr. James MacDonnell, Robert Bradshaw, Henry Joy, and Robert Simms. Edward Bunting, a young classically trained organist, was commissioned to notate the forty tunes performed by ten harpists attending, work that was to form the major part of his General Collection of the Ancient Irish Music (1796). The venue of the contest was in The Assembly Room on Waring Street in Belfast which was opened as a market house in 1769.
