The Lithuanian National Revival, alternatively the Lithuanian National Awakening or Lithuanian nationalism, was a period of the history of Lithuania in the 19th century at the time when a major part of Lithuanian-inhabited areas belonged to the Russian Empire. It was expressed by the rise of self-determination of the Lithuanians that led to the formation of the modern Lithuanian nation and culminated in the re-establishment of an independent Lithuanian state. The most active participants of the national revival included Vincas Kudirka and Jonas Basanavičius. The period largely corresponded to the rise of romantic nationalism and other national revivals of 19th-century Europe.

Lithuanian is an East Baltic language belonging to the Baltic branch of the Indo-European language family. It is the language of Lithuanians and the official language of Lithuania as well as one of the official languages of the European Union. There are approximately 2.8 million native Lithuanian speakers in Lithuania and about 1 million speakers elsewhere. Around half a million inhabitants of Lithuania of non-Lithuanian background speak Lithuanian daily as a second language.
