The vice-president of the Executive Council (Irish: Leas-Uachtarán na hArd-Chomhairle) was the deputy prime minister of the 1922–1937 Irish Free State, and the second most senior member of the Executive Council (cabinet). Formally the vice-president was appointed by the Governor-General on the nomination of the president of the Executive Council, but by convention the Governor-General could not refuse to appoint a vice-president whom the president had selected.

The office of Vice President of the Executive Council was established with the establishment of the Free State in 1922. Under Article 53 of the Free State constitution the role of the vice president was to "act for all purposes in the place of the President", until the appointment of a successor in the event of his death, resignation or "permanent incapacity", or until his return in the event of his "temporary absence". However, in practice the vice president also held a second ministerial portfolio, whose duties he carried out when not called upon to become acting head of government. The president did not have the authority to advise the Governor-General to dismiss the vice president. Rather, as was the case with all other ministers, the entire Executive Council had to be dismissed and reformed en bloc if a president wanted to dismiss the vice president.

This government existed until the Austria-Hungary breakup and the Kingdom of Serbs, Croats and Slovenes' creation in 1918. In 1939, the Banovina of Croatia was established and a head of the Banovina of Croatia (Ban) was appointed by the crown, but no effective government was formed before World War II. In 1943, the ZAVNOH established an executive board to act as a new government. The Socialist Republic of Croatia, as a part of federal Yugoslavia, had a separate government (from 1953 to 1990 known as the Executive Council, appointed by the Sabor) with limited powers (excluding defence and foreign relations; this was similar to all the previous governmental forms). Following the first multi-party elections and the adoption of the present Constitution of Croatia in 1990, the present governmental form was adopted and Stjepan Mesić became the first person to lead a non-communist government (under Government of Yugoslavia), while Josip Manolić was the first prime minister of an independent Croatia. Since the introduction of multi-party democracy, the Republic of Croatia has had fourteen governments headed by twelve different prime ministers. Nine governments have been formed by the Croatian Democratic Union, three by the Social Democratic Party of Croatia, one was headed by a non-partisan prime minister and one was a national unity government (formed during the Croatian War of Independence's peak).
