His Majesty's Solicitor General for England and Wales, known informally as the Solicitor General, is one of the law officers of the Crown in the government of the United Kingdom. They are the deputy of the Attorney General, whose duty is to advise the Crown and Cabinet on the law. They can exercise the powers of the Attorney General in the Attorney General's absence. Despite the title, the position is usually held by a barrister as opposed to a solicitor.

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.
