De Montfort Hall is the largest music and performance venue in Leicester, England. It is situated adjacent to Victoria Park and is named after the "Father of Parliament", Simon de Montfort, Earl of Leicester.

Simon de Montfort, 6th Earl of Leicester, later sometimes referred to as Simon V de Montfort to distinguish him from his namesake relatives, was an English nobleman of French origin and a member of the English peerage, who led the baronial opposition to the rule of King Henry III of England, culminating in the Second Barons' War. Following his initial victories over royal forces, he became de facto ruler of the country, and played a major role in the constitutional development of England.
