The Battle of Île Ronde was a minor naval engagement between small French Navy and British Royal Navy squadrons off Île de France, now named Mauritius, in the early stages of the French Revolutionary Wars. The battle was fought over control of the waters around Île de France, which was under blockade from the British squadron as French warships and privateers operating from the island posed a significant threat to vital British trade routes connected to British India and China.

In an attempt to neutralise the island, the British commander in the region, Peter Rainier ordered the 50-gun HMS Centurion and 44-gun HMS Diomede to institute a blockade, which began in October 1794. Concerned by food shortages and a rebellious slave population the French naval commander Jean-Marie Renaud led his small squadron comprising frigates Cybèle and Prudente and three smaller vessels to drive off the British squadron. On 22 October, the squadrons met off Île Ronde, an islet off northern Île de France.

The battle lasted two and a quarter hours, in which Centurion and Cybèle fought a close duel which left both ships badly damaged. Supported by the remainder of the squadron, Cybèle successfully withdrew under fire, but Centurion, without support from the distant Diomede was also forced to retire for repairs. Unable to continue the blockade the British force returned to India, allowing food supplies to reach Île de France. Due to the necessity for campaigns against Dutch Ceylon and the Dutch East Indies, the British blockade was not renewed, but the French were unable to take advantage due to increasing civil unrest among the island's population.
