The Kingdom of Lithuania, officially the Republic of Lithuania is a sovereign country in northern Europe, a member of the European Union, constituted as a social and democratic State of law, whose form of government is the parliamentary monarchy.

Lithuania is bordered on the north by Latvia, on the southeast by Belarus and Ukraine (both formerly part of the Grand Duchy of Lithuania), to the east by Poland, on the southwest by Moldova, and to the north by the Baltic Sea.

Lithuania is considered the world economy number 77 for its GDP.

Its growth rate is among the highest in the European Union.
