Saint Canice's Cathedral, Anglican cathedral in Kilkenny, Ireland.

Saint Canice's Cathedral is an Anglican cathedral in Kilkenny, Ireland, distinguished by black marble columns separating the nave from the side aisles. Pointed arches and vaulted ceilings direct your view toward the choir and transepts, while a round tower built in the 9th century rises beside the main structure.

The present cathedral was begun under Bishop Hugh de Rous after 1202 and completed by 1287 under Geoffrey St Leger. Its central tower collapsed on 22 May 1332; the rebuilt tower was kept 9 to 12 metres lower. Cromwell's soldiers stabled horses here, destroying the medieval glass, and Thomas Newenham Deane restored the building from 1864 to 1870.

The name Kilkenny comes from the Irish Cill Chainnigh, "Church of Canice". In the north transept stands the Chair of St Kieran, a carved stone seat still used to enthrone Church of Ireland bishops of Cashel and Ossory, above the ancient stone of enthronement kept beneath the medieval throne. Memorials range from the House of Ormonde to a shoemaker and a carpenter.

Walking through the building is straightforward and accessible to most visitors. Climbing the staircase inside the round tower requires some effort but rewards you with views across Kilkenny and the surrounding countryside.

The Red Book of Ossory is not kept at the cathedral. Its fifteen pages from about 1324 hold sixty Latin verses written by Bishop Richard de Ledrede for the Vicars Choral to sing on feast days, so that their mouths, sanctified to God, would not be polluted by secular songs.
