Panama is a narrow, S-shaped country in Central America best known as the site of the Panama Canal, the artificial waterway that joins the Atlantic and Pacific Oceans and reshaped global trade for more than a century.

Where Is Panama Located?

Panama sits at the narrowest point of the land bridge connecting North and South America, bordered by Costa Rica to the west and Colombia to the southeast, with the Caribbean Sea to the north and the Pacific Ocean to the south. Its capital and largest city is Panama City. The country covers about 75,205 square kilometers (29,037 square miles), and its population was estimated at roughly 4.57 million in 2025.

Panama’s Geography and Natural Environment

Because Panama forms a land bridge between two continents, it carries an outsized share of the hemisphere’s biodiversity. According to the Smithsonian Tropical Research Institute, there are more species of birds and plants in Panama, a country roughly the size of South Carolina, than in all of Canada and the United States combined. That same land bridge allowed plants and animals to migrate between North and South America in what scientists call the Great American Biotic Interchange.

Panama’s position also separates two very different oceans. The Caribbean side supports coral reef ecosystems, while the Pacific side experiences nutrient-rich upwelling that sustains abundant marine life, and the country’s tropical location produces distinct wet and dry seasons rather than the four-season pattern of temperate regions.

A Brief History of Panama

Indigenous peoples inhabited the isthmus long before European contact. Spanish colonization began in the early 1500s, and for roughly three centuries the isthmus functioned as Spain’s principal crossing point between its American colonies and Europe. That role is documented by UNESCO’s 2025 inscription of the Colonial Transisthmian Route of Panama, a serial World Heritage property that includes fortified settlements, historic towns, and roads used from the 16th century onward to move people and goods across the isthmus, including the Camino de Cruces, which later shaped the routes of the Panama Railroad and the canal itself. UNESCO notes the property also documents centuries of contact, not always peaceful, among Indigenous peoples, enslaved Africans, and European colonizers.

Independence and the Path to Nationhood

Panama declared independence from Spain in 1821 and united with Gran Colombia, remaining part of Colombia through most of the 19th century. On November 3, 1903, Panama declared independence from Colombia with the support of the United States. The U.S. State Department’s historical record shows that Washington recognized the new government within days, and President Theodore Roosevelt received Panama’s first diplomatic representative on November 13, 1903. In 1904 the two countries signed a treaty giving the United States the right to build and operate a canal across the isthmus and to administer a canal zone around it.

Building the Panama Canal

France made the first serious attempt to build a canal. According to records held by the U.S. National Archives, the Compagnie Universelle du Canal Interoceanique was incorporated under French law on March 3, 1881, but was declared bankrupt and dissolved in February 1889. A successor French company, formed in 1894, ultimately sold its rights and equipment to the United States on April 23, 1904.

American construction began that same year and continued until the canal opened in 1914. Rather than the sea-level design the French had attempted, engineers built a lock canal that lifts ships to Gatun Lake, roughly 26 meters above sea level, over a route of about 80 kilometers (50 miles) between the two oceans, according to the Panama Canal Authority. The National Archives records show that canal administration passed through several U.S. government structures over the following decades, from the original Panama Canal organization (1914 to 1951) to the Canal Zone Government and Panama Canal Company (1951 to 1979) and finally the Panama Canal Commission, established in 1979.

From U.S. Control to Panamanian Sovereignty

U.S. control of the Canal Zone remained a source of tension for decades; relations between the two countries were even severed in 1964 following violence in the zone, according to the State Department’s historical account. That tension was resolved diplomatically on September 7, 1977, when Panama and the United States signed the Torrijos-Carter Treaties, a Neutrality Treaty and a Panama Canal Treaty that set a timetable for transferring the waterway to Panama. The U.S. Senate ratified both agreements in 1978. Under the treaties, the Canal Zone ceased to exist on October 1, 1979, and full control of the canal passed to Panama on December 31, 1999.

Panama prepared for that transition by amending its constitution in 1994 and passing an organic law in 1997 to create the Panama Canal Authority, the autonomous government agency that has run the canal ever since. The period surrounding the handover was turbulent domestically as well, with military rule giving way to a return to democracy after 1989.

Panama’s Government and Economy Today

Panama is a multiparty republic with a president and a single-chamber National Assembly. Its currency, the balboa, is pegged to and circulates alongside the U.S. dollar.

The economy is heavily service-based. According to the World Bank, growth reached 4.4 percent in 2025, driven largely by trade, transport, logistics, and financial services connected to the canal, with growth projected to ease to about 3.9 percent in 2026 before rising toward 4.1 percent in 2027 and 2028. Panama’s gross domestic product was about $90.46 billion in 2025, with per capita GDP near $19,790.

Public finances have improved but remain strained: the fiscal deficit fell from 7.4 percent of GDP in 2024 to 3.7 percent in 2025, while public debt stood at roughly 65.6 percent of GDP as of December 2025, per the World Bank. Poverty, measured at $8.30 per day in 2021 purchasing-power terms, affected about 19.1 percent of Panamanians in 2025, down slightly from 19.8 percent the year before. The World Bank attributes persistently high poverty to labor market informality and weak job quality even amid economic growth. About 66 percent of Panama’s population lives in urban areas.

Panama’s Culture and People

Panama’s population reflects centuries of mixing among Indigenous peoples, Spanish colonizers, and Africans brought to the isthmus, along with later migration tied to canal construction. Spanish is the official language, and English and Indigenous languages are also spoken, according to Encyclopaedia Britannica.

Panama holds five properties on the UNESCO World Heritage List:

• Fortifications on the Caribbean Side of Panama: Portobelo-San Lorenzo (inscribed 1980)
• Darien National Park (inscribed 1981)
• Talamanca Range-La Amistad Reserves, shared with Costa Rica (inscribed 1983, extended 1990)
• Coiba National Park and its Special Zone of Marine Protection (inscribed 2005)
• The Colonial Transisthmian Route of Panama (inscribed 2025)

Together, these sites capture two sides of Panama’s identity: a colonial crossroads shaped by centuries of transisthmian trade, and one of the most biologically rich stretches of tropical forest and coastline in the Americas.

What Is Panama Best Known For?

Above all, Panama is known for its canal. In 2024 the waterway handled more than 210 million long tons of cargo across 11,240 commercial transits, according to Encyclopaedia Britannica, a sharp rise in tonnage from the traffic peak of 15,523 transits recorded back in 1970, reflecting today’s larger vessels. The Panama Canal Authority reports that between 13,000 and 14,000 ships use the canal each year, serving more than 180 maritime routes and connecting 1,920 ports across 170 countries.

Britannica describes canal traffic as “a barometer of world trade,” since volumes rise during periods of global economic expansion and fall during downturns. Panama is also recognized for its exceptional biodiversity relative to its size and for its position as a regional logistics and financial hub built around the canal.

Why Panama Matters Globally

Panama’s importance extends well beyond its borders because so much of world trade depends on a single crossing point it controls. Major shipping corridors, including routes linking the U.S. East Coast to East Asia, rely on the canal to avoid the much longer voyage around South America. That dependence gives a small country outsized influence over global shipping costs and schedules.

The 1977 treaties and the 1999 handover also stand as a notable example of a nation regaining full sovereignty over strategic infrastructure through negotiated diplomacy rather than conflict. Scientifically, Panama’s role as a land bridge between continents continues to draw international research through institutions such as the Smithsonian Tropical Research Institute, which uses the isthmus to study how species migrate, adapt, and diverge when continents and oceans meet.
