Clonbulloge (Irish: Cluain Bolg) is a village in County Offaly, Ireland. Bolg was the Celtic sun-god and this was probably a field where followers of Bolg assembled for worship.^{[citation needed]} The common pronunciation of the village up to recent times was 'Clon Bolg', which endorses this interpretation.^{[citation needed]} It has been voted the tidiest town in County Offaly every year since 1978.^{[citation needed]}

The village is located at the junction of the R401 and R442 regional roads. The Figile River runs through the village under the R442 near its confluence with the Philipstown River.

Between the village and Edenderry, 11 km to the north, lies the Bog of Allen.

Clonbullogue is located near the point where three counties—Offaly, Laois and Kildare meet. The village is on an island of pasture land in the bog of Allen. The population of the village is 442, which has remained almost unchanged for over a century.

The area is marked on the Cottonian map 1653 of Leix & Offaly as Clanbolg. In the 1659 Census, Robert Shallcross was listed as the titled person in the area. In 1679, Charles II granted this area to the Purefoy family and for a time the village was called Purefoy's Place.^{[citation needed]} In 1798, the village was burned—the only part of Offaly to suffer this fate during the Rebellion. Two of the Wexford leaders, Colonel Anthony Perry and Father Mogue Kearns were captured here and were later hanged at Edenderry for their part in the 1798 Rebellion.
