Executive Council of New Brunswick

The Executive Council of New Brunswick (), informally and more commonly, the Cabinet of New Brunswick (), is the Cabinet of the Canadian province of New Brunswick.

Almost always made up of members of the Legislative Assembly of New Brunswick, though not necessarily so, New Brunswick's Cabinet is similar in structure and role to the federal Cabinet of Canada, while being smaller in size. As federal and provincial responsibilities and areas of jurisdiction differ, there are a number of different portfolios between the federal and provincial governments. For example, education being a provincial domain, New Brunswick has a Minister of Education, while the federal Cabinet would not.

The Lieutenant-Governor of New Brunswick, as representative of the King in Right of New Brunswick, appoints the Premier and the Executive Council of whichever party forms government in a given legislature, which exists to advise them on the governance of the Province. The term "Lieutenant-Governor in Council" refers to the Lieutenant-Governor acting on the recommendations of Cabinet, though they have no real decision-making authority. Members of the Executive Council, called Cabinet Ministers, are appointed on the recommendation of the Premier, at whose pleasure they serve, and each oversees a certain area of the provincial government, called a "portfolio". Some Ministers head entire government departments ("Minister of ..."), while others are responsible for parts of departments or cross-government initiatives ("Minister responsible for ...").

The Cabinet meets on a weekly basis during the fall, winter and spring, and a monthly basis during the summer, at which Ministers and the Premier discuss policy matters and the governance of the Province. Such meetings are confidential, under the principle of "Cabinet confidentiality", and Ministers must agree to present a united front based on whichever decision is taken. Government departments will often bring proposals to Cabinet for direction or approval (for example, to draft a Bill or enter into an agreement), on which Cabinet will issue a decision and, where applicable, provide a recommendation to the Lieutenant-Governor for issuing an Order-in-Council.

There are currently two committees within the Cabinet: Policy and Priorities Board, which studies strategic and policy matters and is chaired by the Premier, and Treasury Board, which studies financial and administrative matters and is chaired by the Minister of Finance. The two committees may also hold a joint meeting. There was previously a COVID-19 Cabinet Committee, which, uniquely, included members from all parties in the New Brunswick Legislative Assembly. However, in late 2021, committee members from the Green and Liberal parties quit the committee over a controversy in which the provincial government had issued an emergency order forcing striking healthcare workers back to work.
