The Spanish government departments, commonly known as Ministries, are the main bodies through which the Government of Spain exercise its executive authority. They are also the top level of the General State Administration. The ministerial departments and their organization are created by Royal Decree signed by the Monarch and the Prime Minister and all of them are headed by a Cabinet member called Minister.
Although the main organization is established by the Premier, the ministers have autonomy to organize its own department and to appoint the high-ranking officials of the ministries. It exists the possibility of ministers without portfolio, which are minister-level officials entrusted with a specific task and that do not head a department.
As of 2024, there are currently 22 ministerial departments.
