The Battle of Makassar Strait, also known as the Action of Madura Strait, the Action North of Lombok Strait and the Battle of the Flores Sea, was a naval battle of the Pacific theater of World War II. An American-British-Dutch-Australian (ABDA) fleet—under Schout-bij-nacht (Rear Admiral) Karel Doorman—was on its way to intercept a Japanese invasion convoy reported as bound for Surabaya (its destination was actually Makassar), when it was attacked by 36 Mitsubishi G4M1 "Betty" and 24 Mitsubishi G3M2 "Nell" medium bombers, which forced the fleet to retreat.

The battle occurred on 4 February 1942 in the Java Sea, closer to the Kangean Islands than to Makassar Strait. This battle should not be confused with the Battle of Balikpapan, which occurred over a week earlier on 24 January 1942, which is also sometimes referred to as the "Battle of Makassar Strait".
