Mullinahone (Irish: Muileann na hUamhan, meaning 'Mill of the river, mill of the cave') is a village located in the barony of Slievardagh, County Tipperary in Ireland.

It is located in a low-lying broad valley area, for the most part, two to three hundred feet above sea level in South-East Tipperary.

This has 'karst' features, which means that it is fissured with many caves and underground streams, subjecting some areas to flooding in times of heavy rainfall.

[citation needed] The name of Mullinahone appears first as a settlement in the records of the "Hearth Money Rolls" in the years 1665 to 1667, then spelled as Moninehoan.

It was entered as a village or settled area of nine 'cabbins' with hearths, that is, permanent structures, which were not very common then it appears after the wars of the time.

Both were extensions of the worker/artisan settlements of Killaghy Castle and lands whose estate walls adjoin the modern town today.

[citation needed] The modern parish was formed in the 18th century as the Catholic Church was re-organised when Penal Laws were relaxed.

The old Gaelic entity of Compsey extended as far as Glenbower and Ahenny in Grangemockler parish and also part of Cloneen and adjoining areas.

One of the first Tobins was instructed to cut down the woods of Killaghy by royal decree to "ensure safe passage for travellers" i.e. the army and supplies.

The army of William of Orange camped near Mullinahone in 1691, and an order went out to 'burn the Compsey' as it was believed to harbour rapperees or highway men.

[citation needed] During the rebellion of 1798, there was an uprising on Carraigmoclear hill on Slievenamon, ending in defeat for the local men.
