An ombudsman (//, also US: /- - -/-,,), ombudsperson, ombud, ombuds, or public advocate is an official who is usually appointed by the government or by parliament but with a significant degree of independence. In some countries, an inspector general, citizen advocate or other official may have duties similar to those of a national ombudsman and may also be appointed by a legislature. Below the national level, an ombudsman may be appointed by a state, local, or municipal government. Unofficial ombudsmen may be appointed by, or even work for, a corporation such as a utility supplier, newspaper, NGO, or professional regulatory body.
The typical duties of an ombudsman are to investigate complaints and attempt to resolve them, usually through recommendations (binding or not) or mediation. Ombudsmen sometimes also aim to identify systemic issues leading to poor service or breaches of people's rights. At the national level, most ombudsmen have a wide mandate to deal with the entire public sector, and sometimes also elements of the private sector (for example, contracted service providers). In some cases, there is a more restricted mandate, for example with particular sectors of society. More recent developments have included the creation of specialized children's ombudsmen.
In some jurisdictions an ombudsman charged with handling concerns about national government is more formally referred to as the "parliamentary commissioner" (e.g. the United Kingdom Parliamentary Commissioner for Administration, and the Western Australian state Ombudsman). In many countries where the ombudsman's responsibility includes protecting human rights, the ombudsman is recognized as the national human rights institution. The post of ombudsman had by the end of the 20th century been instituted by most governments and by some intergovernmental organizations such as the European Union.
