Largest Countries in Oceania by Area 2018

Not surprisingly, the largest country in the world by area is Russia, spanning a huge 17,098,242 km² across Eastern Europe and Asia. This is followed by Canada (9,984,670 km²) and China (9,706,961 km²), both much smaller although still very large, while the United States and Brazil complete the top five at 9,372,610 km² and 8,515,767 km² respectively, putting a total of three countries in the Americas in the world's top five largest.

The largest country by landmass in Asia is India, at 3,287,590 km², while the smallest is Macau, an autonomous region on the south coast of China that is just 30 km². Africa's largest country is Algeria (2,381,741 km²) and its smallest is the Indian Ocean archipelago of Mayotte (374 km²). While Russia is on the European land mass, France is Western Europe's largest country at 551,695 km²; however, it only just makes it into the top fifty, so it is comparatively quite small.

The smallest countries in the world are predominantly in Europe, Oceania and the Americas, and many are island nations, some of which are constituent territories of other countries. Vatican City is the smallest in the world at a tiny 0.44 km², followed by Monaco at 2.02 km² and Gibraltar at 6 km². They are followed by Tokelau (12 km²) and Nauru (21 km²), both in the Oceania region. The smallest country in the Americas are the Caribbean islands of Sint Maarten and Saint Martin, at 34 and 53 km², respectively.
