The Executive Council of Newfoundland and Labrador is the cabinet headed by the lieutenant governor and composed of the ministers in office. The Executive Council is composed only of ministers in office, and is the official body by which Cabinet's constitutional advice is given to the lieutenant governor.

By the arrangements of the Canadian federation, the Canadian monarchy operates in Newfoundland and Labrador as the core of the province's Westminster-style parliamentary democracy. As such, the Crown within Newfoundland and Labrador's jurisdiction is referred to as the Crown in Right of Newfoundland and Labrador, His Majesty in Right of Newfoundland and Labrador, or the King in Right of Newfoundland and Labrador. The Constitution Act, 1867, however, leaves many royal duties in the province specifically assigned to the sovereign's viceroy, the lieutenant governor of Newfoundland and Labrador, whose direct participation in governance is limited by the conventional stipulations of constitutional monarchy.
