This is a '''list of islands of Ireland'''. [[Ireland]] is itself an island, lying west of the island of [[Great Britain]] and northwest of [[Continental Europe|mainland Europe]].

The [[Hebrides]] off [[Geography of Scotland|Scotland]] and [[Anglesey]] off [[Geography of Wales|Wales]] were grouped with Ireland ("[[Hibernia]]") by the [[Greek people|Greco]]-[[Ancient Romans|Roman]] [[Ancient Greek geography|geographer]] [[Claudius Ptolemy|Ptolemy]],<ref>{{citation |author=[[Ptolemy]] |title=[[Ptolemy's Geography|Geog.]] |at=Bk. 2, Ch. 1 & 2 }}.</ref> but this was not geographically correct and is purely of historical interest.

==Total population of Irish offshore islands==
The number of people living on Irish offshore islands decreased dramatically during the [[Irish famine]] and the period following it. Since then the trend on most islands has been a decreasing population until the 1950s and 1960s, during which many islands were forcibly evacuated by the [[Irish Government]] as continuous bad weather meant that islanders were unable to travel to the mainland for several consecutive months. Of the remaining islands that were not evacuated, many of their populations have continued to dwindle ever since, with some seeing stabilisation or even a slight increase in population during and after the [[Celtic Tiger]].

The chart below shows the total number of people living on Irish islands throughout the years.
