The largest country in the world by total land area is Russia, which covers approximately 17,098,242 square kilometers (6,601,668 square miles). This massive nation spans two continents—Europe and Asia—and encompasses 11 different time zones, stretching from the Baltic Sea in the west to the Pacific Ocean in the east. Russia's sheer size accounts for about 11% of the total landmass of the Earth, making it nearly double the size of the second-largest country, Canada. Its vast geography includes a diverse range of environments, from the frozen tundra and boreal forests (taiga) of Siberia to the rolling plains of the European heartland and the high mountain ranges of the Caucasus. Despite its immense area, Russia's population remains concentrated in the European portion of the country, while much of its Asian territory is sparsely inhabited due to the extreme arctic and sub-arctic climates. In 2026, Russia's vast natural resources, particularly its timber, minerals, and natural gas reserves located within this enormous land area, remain a critical component of the global economy and its geopolitical influence.
