The Law Officers are the senior legal advisors to His Majesty's Government of the United Kingdom and devolved governments of Northern Ireland, Scotland and Wales. They are variously referred to as the Attorney General, Solicitor General, Lord Advocate, or Advocate General depending on seniority and geography - though other terms are also in use, such as the Counsel General for Wales. Law Officers in these roles are distinguished by being political appointees, while also being bound by the duties of independence, justice and confidentiality among the other typical professional commitments of lawyers. These roles do not have any direct oversight of prosecutions nor do they directly lead or influence criminal investigations. This is a distinguishing factor between Law Officers and the State Attorneys General of the United States or US Attorney General.

The Counsel General for Wales is the Welsh Government's Law Officer, which means the government's chief legal adviser and representative in the courts. In addition to these "lawyer" roles the Counsel General also works to uphold the rule of law and integrity of the legal community in Wales, and has a number of important specific statutory functions, some of which are to be exercised independently of government and in the public interest.
