Natural Heritage Area (Irish: Limistéar Oidhreachta Nádúrtha) is a conservation designation denoting a protected area in Ireland. The Wildlife (Amendment) Act 2000 makes legal provision for the designation and protection of a national network of Natural Heritage Areas (NHAs).
The designation is currently used by the National Parks and Wildlife Service (NPWS) to protect wildlife habitats, such as raised bogs. 75 raised bogs were designated for protection in 2004 under the Wildlife Act.
