The village takes its name from the Irish An Chloc which means "stone" or "stone building". The original townsland name was Magleitid (Broad plain). History tells of a castle sited in the "Castle field" in the townland of Coultha; this may be where Clogh derived its name.

Clogh was historically a more densely populated area, mostly due to the employment given in the local coal mines. Coalmining began in the 1640s by Christopher Wandesforde. The coal produced was a high grade anthracite with low sulphur content. Situated in the Leinster coal–fields which spread into counties Laois and Carlow, by the late 1800s seven or eight mines existed, and in Deerpark mines opened in the 1920s and at its peak employed 600 people. A number of coal-mining families from the area emigrated to Heckscherville, Pennsylvania during and after the Great Famine of 1845–1851. The Payne brothers, who ran the coal pits, came to the area of North Kilkenny and Laois to recruit miners for their mines. They provided transportation, employment and homes to those who agreed to move. The mines, in the Clogh area, closed in 1969.

The first church in Clogh was built on the site of the present church in the 13th century. This replaced the ancient church that stood at Kilpatrick. The present church was built in 1826. The graveyard is large and contains monuments, including one to Michael Fenlon who constructed the first Boulton & Watt steam engine for use in the nearby Doonane Colliery (1793/94). Fenlon was a lecturer in Trinity College, Dublin, he died at the young age of 36 years. Moneenroe Catholic Church was built in 1928 and cost twelve thousand pounds with the local miners contributing six thousand pounds. The Colliery Church was consecrated in 1829 and serves the Church of Ireland Community in the area.
