Liechtenstein, officially the Principality of Liechtenstein, is a doubly landlocked German-speaking microstate located in the Alps between Austria and Switzerland. Liechtenstein is a semi-constitutional monarchy headed by the prince of Liechtenstein of the House of Liechtenstein, currently led by Hans-Adam II. Liechtenstein is bordered by Switzerland to the west and south and Austria to the east and north. It is Europe's fourth-smallest country, with an area of just over 160 square kilometres and a population of 39,790. It is the world's smallest country to border two countries.

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.
