A commissioner (commonly abbreviated as Comm'r) is, in principle, a member of a commission or an individual who has been given a commission (official charge or authority to do something).

In practice, the title of commissioner has evolved to include a variety of senior officials, often sitting on a specific commission. In particular, the commissioner frequently refers to senior police or government officials. A high commissioner is equivalent to an ambassador, originally between the United Kingdom and the Dominions and now between all Commonwealth states, whether Commonwealth realms, republics or countries having a monarch other than that of the realms. The title is sometimes given to senior officials in the private sector; for instance, many North American sports leagues.

There is some confusion between commissioners and commissaries because other European languages use the same word for both. Therefore titles such as commissaire in French, Kommissar in German and comisario in Spanish or commissario in Italian, can mean either commissioner or commissary in English, depending on the context.

Domestic public official A commissioner within a modern state generally holds his or her office by a commission from the head of state or a council of elected representatives (or appointed by non-elected officials in the case of dictatorships).

Canadian territories

Commissioners are the formal heads of the territories in Canada (those areas under the formal jurisdiction of the federal Crown-in-Council without separate constitutional status of a province). Unlike the governor general or a lieutenant governor, commissioners are not viceregal representatives of the Canadian monarch; rather, they are delegates of the federal Crown-in-Council and, under federal statutes governing the territories,Northwest Territories Act, enacted as s. 2 of the Northwest Territories Devolution Act, S.C. 2014, c. 2.Yukon Act, S.C. 2002, c. 7, as it appeared on 2020‑03‑05.Nunavut Act, S.C. 1993, c. 28, as it appeared on 2020‑03‑05. act following written instructions from Cabinet or the minister responsible (currently the minister of northern affairs). While commissioners formerly had a direct day-to-day role in administration and government and chaired the territory's executive council, today they are under instruction to act more like provincial lieutenant governors, as territorial assemblies have taken on more responsibility. Commissioners thus perform ceremonial duties similar to those of the monarch and viceroys, including reading the speech from the throne at the opening of the territorial legislature and presenting commendations to Canadian Forces members for long-term or outstanding service to the office. Possible candidates for the position are selected by the Advisory Committee on Vice-Regal Appointments. The official appointment is made by the Governor General-in-Council (the federal government).

In other countries, such as Latin American countries, France, Germany, Austria, the Netherlands, Luxembourg, Spain, Italy, etc., a commissioner is typically the commander of a major police station or a locally/regionally important police service.

European Union The European commissioners are the members of the European Commission, the cabinet of the European Union. Commissioners’ role closely resembles that of the ministers of the Union’s member states; each is assigned a portfolio under the authority of the president of the EU Commission, but they make important decisions collegially, often subject to approval by the European Parliament and/or the Council of the European Union, the two organs of the EU’s bicameral legislature.
