Slovakia, officially the Slovak Republic, is a landlocked country in Central Europe. It is bordered by Poland to the north, Ukraine to the east, Hungary to the south, Austria to the west, and the Czech Republic to the northwest. Slovakia's mostly mountainous territory spans about 49,000 square kilometres (19,000 sq mi), hosting a population exceeding 5.4 million. The capital and largest city is Bratislava, while the second largest city is Košice.

A landlocked country is a country that does not have territory connected to an ocean or whose coastlines lie solely on endorheic basins. Currently, there are 44 landlocked countries, two of them doubly landlocked, and three landlocked de facto states in the world. Kazakhstan is the world's largest landlocked country, while Ethiopia is the world's most populous landlocked country.
