The Battle of Cuddalore in 1783 was a naval battle between a British fleet, under Admiral Sir Edward Hughes with Admiral L.J. Weiland, and a smaller French fleet, under the Bailli de Suffren, off the coast of India that took place right before the Treaty of Paris that ended the American Revolutionary War. This war sparked the Second Mysore War in India. In the battle, taking place near Cuddalore on 20 June 1783, Suffren commanded the engagement from the frigate Cléopâtre and won what is generally considered a victory. Peace had already been agreed upon in Europe, but that news had yet to reach India, making this the final battle of the war.

Cuddalore, also spelt as Kadalur, is the city and headquarters of the Cuddalore District in the Indian state of Tamil Nadu. Situated south of Chennai, Cuddalore was an important city and port during the British Raj.
