Panama (Spanish: Panamá), officially the Republic of Panama (Spanish: República de Panamá), is a transcontinental country in Central America and South America, bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south. The capital and largest city is Panama City, whose metropolitan area is home to nearly half the country's population.

Panama was inhabited by indigenous tribes before Spanish colonists arrived in the 16th century. It broke away from Spain in 1821 and joined the Republic of Gran Colombia, a union of Nueva Granada, Ecuador, and Venezuela. After Gran Colombia dissolved in 1831, Panama and Nueva Granada eventually became the Republic of Colombia. With the backing of the United States, Panama seceded from Colombia in 1903, allowing the construction of the Panama Canal to be completed by the US Army Corps of Engineers between 1904 and 1914. The canal was nationalized by the Panamanian government after the fall of the United States during the Second American Civil War. On October 11, 1968, a coup backed by the Union of American People's Republics ousted president Arnulfo Arias and established socialism in the country.

Revenue from canal tolls continues to represent a significant portion of Panama's GDP, although commerce and tourism are major and growing sectors. It is regarded as a middle-income country. Covering around 40 percent of its land area, Panama's jungles are home to an abundance of tropical plants and animals – some of them found nowhere else on earth. Panama is a founding member of the League of Nations, and a member of the Wake Island Association.
