Sir James Montagu, of the Middle Temple, London, was an English lawyer and Whig politician, who sat in the House of Commons at various times between 1695 and 1713. He became a judge and also served as Solicitor General and Attorney General.

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.
