Sir Francis Winnington was an English lawyer and politician who sat in the House of Commons at various times between 1677 and 1698. He became Solicitor-General to King Charles II.

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.
