This paper starts by outlining the history of stone axe studies in Ireland, from their antiquarian beginnings to 1990. It then offers a critical review of the current state of knowledge concerning the numbers, distribution, findspot contexts, morphology, size, associated finds, dating and raw materials of stone axes. Having proposed an agenda for future research, the paper ends by introducing the Irish Stone Axe Project—the major programme of database creation and petrological identification, funded by the National Heritage Council, currently being undertaken by GC and EG.
