The Siege of Madras is a siege of Madras, British India, between December 1758 and February 1759 by French forces under the command of Lally during the Seven Years' War.

The British garrison is able to hold out until it is relieved.

The British fire 26,554 cannonballs and more than 200,000 cartridge rounds in defense of the town.

The failure to take Madras is a huge disappointment for the French and a massive setback to their campaign in India, compounded by the later Battle of Wandiwash.

The British victory helps contribute to the Annus Mirabilis of 1759.
