The Portuguese conquest of French Guiana, also known as Conquest of Cayenne (Portuguese: Conquista de Caiena), was the capture of the French colony of Cayenne by Anglo-Portuguese forces in January 1809 during the Napoleonic Wars. It formed part of the Caribbean campaign of 1803–1810, a British-led campaign against the colonies of France and its allies during the conflict. As Britain was unable to sent substantial forces to attack Cayenne due to military commitments elsewhere, the British requested the Portuguese government, which had fled from Portugal to Brazil in November 1807, to launch an attack on the colony. Britain promised the Portuguese that they would control Cayenne for the duration of the conflict in exchange for carrying out the requested invasion.
