The Invasion of Java in 1811 was a successful British amphibious operation against the Dutch East Indian island of Java that took place between August and September 1811 during the Napoleonic Wars. Originally established as a colony of the Dutch Republic, Java remained in Dutch hands throughout the French Revolutionary and Napoleonic Wars, during which time the French invaded the Republic and established the Batavian Republic in 1795, and the Kingdom of Holland in 1806. The Kingdom of Holland was annexed to the First French Empire in 1810, and Java became a titular French colony, though it continued to be administered and defended primarily by Dutch personnel.

Java is one of the Greater Sunda Islands in Indonesia. It is bordered by the Indian Ocean to the south and the Java Sea to the north. With a population of 151.6 million people, Java is the world's most populous island, home to approximately 56% of the Indonesian population. Indonesia's capital city, Jakarta, is on Java's northwestern coast.
