Edward Richard Montagu, Viscount Hinchingbrooke (7 July 1692 – 3 October 1722) was the eldest son of Edward Montagu, 3rd Earl of Sandwich and his wife Elizabeth, daughter of the Earl of Rochester.
Hinchingbrooke's mother kept his father, who was generally believed to be insane, much confined, leaving Hinchingbrooke to carry out the public business of his family.
On 12 April 1707, at the age of 14, he married Elizabeth Popham (d. 20 March 1761), the daughter of Alexander Popham of Littlecote, Wiltshire (a grandson of Alexander Popham). They had five children:
After a tour of the continent in 1708, Hinchingbrooke was given command of a troop in Sir Richard Temple's Regiment of Horse for the 1709 campaign in Flanders.
During this time, Hinchingbrooke was one of the infamous Mohocks, and was arrested for assaulting a watchman in 1712. In 1713, he was elected to the House of Commons as Member of Parliament for Huntingdon, for which he served until 1722.
He became colonel of the 37th Regiment of Foot in 1717. In March 1722, he was named Lord Lieutenant of Huntingdonshire and was returned as MP for Huntingdonshire in April. However, he died in October 1722, predeceasing his father. His widow later married Francis Seymour.
