Cahir (/ˈkɛər/; Irish: an Chathair / Cathair Dún Iascaigh)[7] is a town in County Tipperary in Ireland.

For much of the twentieth century, Cahir stood at an intersection of two busy national roadways: the Dublin to Cork N8, and the Limerick to Waterford N24.

Traffic from the N24 still left the town badly congested, however, until October 2007 when this road was also realigned to bypass Cahir to the north and east.

[9] Cahir, together with Clonmel, were the centres in South Tipperary of the Quaker population, who constructed a meeting house in Abbey Street in 1833.

[10] It was one of the first towns to be linked by stagecoach in the nineteenth century, when Charles Bianconi commenced services between Clonmel, Cahir and Cashel.

The building at The Square, where The Galtee Inn is now sited, was the stopping point in the town for Bianconi's coaches.

[citation needed] Cahir Castle, which is situated on a small island in the River Suir, is one of the town's main tourist attraction.

The nearby Galtee Mountains form the largest inland range in Ireland and are home to Glengarra Wood,[12] which is a popular walking area.
