William Augustus Montagu (1752–1776) was a British politician who sat in the House of Commons from 1774 to 1776.
[1] It was said of Montagu that he possessed great talents, and by good education had every opportunity of cultivating them.... but [was ruined by] dissipated company, habits of extravagance and total neglect of his health and constitution.
[2] It would appear that Lord Sandwich intended to use his son to support his interest in Parliament when the opportunity arose.
Montagu was returned unopposed as Member of Parliament for Huntingdon at a by-election on 28 February 1774.
[2] His nephew, son of Lord Hinchingbrooke was also called William Augustus Montagu.
