Pilgrim Paths Ireland (PPI) is a non-denominational representative body for Ireland's medieval pilgrim paths. PPI was founded in 2013 to oversee the development and promotion of Ireland's medieval pilgrimage paths, and consists of 12 community groups supporting specific paths. PPI holds an annual National Pilgrimage Paths Week during Easter, and issues a National Pilgrimage Passport to finishers of the 5 main trails: Cnoc na dTobar, Cosán na Naomh, St. Finbarr's Pilgrim Path, St. Kevin’s Way, and Tochar Phádraig.

These are lists of long-distance trails in the Republic of Ireland, and include recognised and maintained walking trails, pilgrim trails, cycling greenways, boardwalk-mountain trails, and interconnected national and international trail systems.
