The Minister for Supplies (Irish: An tAire Soláthairtí) was created by the Ministers and Secretaries (Amendment) Act 1939, to assist Ireland through World War II, or the Emergency, as it was referred to by the Government of Ireland.

[1] Although the legislation creating the new department was not passed until 21 December 1939, it was given retrospective effect, and was deemed to have come into force on 8 September 1939.

According to the historian Bryce Evans, Minister Seán Lemass introduced full rationing in Ireland 'too late', ensuring the black market trumped later state attempts at equitable distribution amid the British wartime supply squeeze.

[3] Earlier historians had pointed to Lemass's successes in stockpiling essential goods.

[citation needed] The minister's functions were transferred to the Minister for Industry and Commerce on abolition of the office on 1 August 1945.
