The prehistory of Ireland has been pieced together from archaeological evidence, which has grown at an increasing rate over the last decades. It begins with the first evidence of permanent human residence in Ireland around 10,500 BC and finishes with the start of the historical record around 400 AD. Both the beginning and end dates of the period are later than for much of Europe and all of the Near East. The prehistoric period covers the Palaeolithic, Mesolithic, Neolithic, Bronze Age and Iron Age societies of Ireland. For much of Europe, the historical record begins when the Romans invaded; as Ireland was not invaded by the Romans its historical record starts later, with the coming of Christianity.

The European Bronze Age is characterized by bronze artifacts and the use of bronze implements. The regional Bronze Age succeeds the Neolithic and Copper Age and is followed by the Iron Age. It starts with the Aegean Bronze Age in 3200 BC and spans the entire 2nd millennium BC, lasting until c. 800 BC in central Europe.
