Carrickmacross (Irish: Carraig Mhachaire Rois, meaning 'rock of the wooded plain')[4] is a town in County Monaghan, Ireland.

[6] The town's Poor Law Union Workhouse and Fever Hospital were built in this period - the latter later becoming the offices of the Urban District Council which was originally formed in 1899.

[14] The grave of Patrick Byrne (1794–1863), the last major exponent of the Gaelic harp and the first Irish traditional musician ever photographed, is in the area.

Carrickmacross lace is worked in an individual style, devised by Mrs Grey Porter, wife of the rector of Donaghmoyne, who introduced it in 1820.

Subsequently, the lacemaking declined, but in the last decade of the 19th century the Sisters of St Louis founded their own lace school to revive the craft, and this was quite profitable for several years.

On 20 December 1940, as well as two bombs falling on Sandycove in Dublin, two more fell on Shantonagh near Carrickmacross, causing minor damage to house property.

The station, and the branch, closed to passengers on 10 March 1947, but remained open for goods traffic until final closure on 1 January 1960.

[19] It was set up by the Patrician Brothers, and was previously situated next to the Church on O'Neills street; that building is now the Scout Hall.

It forms part of the five-seat Carrickmacross Local Electoral Area for elections for Monaghan County Council.
