The siege of Mons was an engagement from 7 June to 23 July 1746 during the War of the Austrian Succession.

[2] The town of Mons, then part of the Austrian Netherlands, was besieged by a French army corps commanded by Louis François, Prince of Conti.

[3] Following the capture of Brussels by Maurice de Saxe in February 1746, a council of war was held in the city to determine the next French course of action.

[3] Against the advice of Saxe, Louis XV endorsed the plan of the Prince of Conti to continue operations by taking the towns of Mons and Charleroi.

Conti, who arrived outside the town on 7 June, directed Joseph Marie de Boufflers and the Count of Estrées to lead the French siege force.
