Anglo-Spanish War: The United Kingdom captured Havana after a five-week siege, holding it until the Treaty of Paris the following year.

The Anglo-Spanish War was fought between Britain and Spain as part of the Seven Years' War. It lasted from January 1762 until February 1763, when the Treaty of Paris brought it to an end.

Havana is the capital and largest city of Cuba. The heart of La Habana Province, Havana is the country's main port and commercial center. It is the most populous city, the largest by area, and the second largest metropolitan area in the Caribbean region. The population in 2021 was 2,142,939 inhabitants, and its area is 728.26 km² (281.18 sq mi) for the capital city side and 8,475.57 km² for the metropolitan zone. Its official population was 1,749,964 inhabitants in 2024.

The siege of Havana was the successful capture of the Spanish-held city of Havana, Cuba in 1762 as part of the war between the two nations which formed part of the larger Seven Years' War. After the Spanish abandoned their former policy of neutrality by signing the family compact with France, Britain declared war on Spain in January 1762. The British government decided to mount an attack on the important Spanish naval base of Havana, with the intention of weakening the Spanish West Indies and improving the security of its own American colonies. A Royal Navy force consisting of squadrons from Britain and the West Indies, escorting 160 troopships, were able to approach Havana from a direction that neither Governor Juan de Prado nor Admiral Gutierre de Hevia expected and were able to trap de Hevia's fleet in the Havana harbour and land their troops with relatively little resistance.

The Treaty of Paris, also known as the Treaty of 1763, was signed on 10 February 1763 by the kingdoms of Great Britain, France and Spain, with Portugal in agreement, following Great Britain and Prussia's victory over France and Spain during the Seven Years' War.
