The Irish state has officially approved the following list of national monuments in County Dublin and the city of Dublin. In the Republic of Ireland, a structure or site may be deemed to be a "national monument", and therefore worthy of state protection unless the government decides to demolish it. If the land adjoining the monument is essential to protect it, this land may also be protected.

Conservation in the Republic of Ireland is overseen by a number of statutory and non-governmental agencies, including those with responsibility for conservation of the built environment and conservation of the natural environment in Ireland. Conservation has sometimes been a contentious issue, with debates impacting its progress since the 1960s. Concrete initiatives are sometimes driven by European Union (EU) heritage protection and environmental policies, including EU environmental law, which – as a member – the Irish government is obliged to adopt and implement.
