The Battle of Tidore in 1536 was a military engagement between the forces of the Portuguese Empire, and those of eight united rulers of the archipelago.

After conducting an amphibious attack on Tidore, the heavily outnumbered Portuguese led by António Galvão assaulted and razed the city of Tidore. The coalition fell apart shortly afterwards and the region submitted to Portuguese rule.
