The Minister for Finance is a senior minister in the Government of Ireland. The Minister for Finance leads the Department of Finance and is responsible for all financial and monetary matters of the state; and is considered the second most important member of the Government of Ireland, after the Taoiseach.

The Constitution of Ireland vests executive authority in the Government of Ireland, which is headed by the Taoiseach, the head of government. The government – also known as the cabinet – is composed of ministers, each of whom must be a member of the Oireachtas, which consists of Dáil Éireann and Seanad Éireann. Most ministers have a portfolio of specific responsibilities such as departments or policy areas, although ministers without portfolio can be appointed.
