Together, the three Regional Assemblies comprise the regional tier of government in Ireland. The Regional Assemblies were established in 2015 under the Local Government Reform Act 2014, each one representing one of the three Irish regions:

Southern Regional Assembly: Southern Region,

Eastern & Midland Regional Assembly: Eastern & Midland Region,

Northern & Western Regional Assembly: Northern & Western Region.

Part of the Local Government sector, the Regional Assemblies forge links between the EU, and national and local levels through regional spatial and economic planning and EU Funding at regional level. Each Regional Assembly is responsible for implementing a Regional Spatial & Economic Strategy for their respective regions.
