The Kingdom of Northern Lusitania (Portuguese: Reino da Lusitânia Setentrional) was a kingdom proposed by Napoleon in 1807 for the king of Etruria, Charles Louis, located in the North of Portugal.

In 1807 Portugal refused Napoleon's demand to accede to the Continental System of embargo against the United Kingdom. Napoleon, having signed the Treaty of Fontainebleau on 27 October 1807, with Spain, defined the occupation of Portugal, proposing that the country would be divided into three different states:

A French invasion under General Junot followed, and the capital city of Lisbon was captured on 1 December 1807. British intervention in the Peninsular War, under Arthur Wellesley, 1st Duke of Wellington, helped to maintain Portuguese independence, the last French troops being expelled in 1812.
