Spancill Hill or Spancilhill (Ordnance Survey spelling Spancel Hill for the hill and settlement, Spancelhill for the electoral division; Irish: Cnoc Uarchoille) is a hill and adjacent dispersed settlement in County Clare, Ireland. The historic hamlet of Spancilhill was by the fair green, which is still the site of the Spancill Hill Fair, Ireland's oldest horse fair, which occurs annually on 23 June. Houses are concentrated slightly south at Cross of Spancilhill, where the R352 road between Ennis to the west and Tulla to the east crosses a local road between Barefield to the north and Quin to the south.
