The national flag of Lithuania (Lithuanian: Lietuvos vėliava) consists of a horizontal tricolour of yellow, green, and red. It was adopted on 25 April 1918 during Lithuania's first period of independence (in the 20th century) from 1918 to 1940, which ceased with the occupation first by the Soviet Union, and then by Nazi Germany (1941–1944). During the post-World War II Soviet occupation, from 1945 until 1988, the Soviet Lithuanian flag consisted first of a generic red Soviet flag with the name of the republic, in 1953 that was changed to the red flag with white and green bands at the bottom.

The flag was then re-adopted on 18 November 1988, about 1.5 years before the re-establishment of Lithuania's independence and almost three years before the collapse of the Soviet Union. The last alteration to the current flag occurred in 2004, when the aspect ratio changed from 1:2 to 3:5.
