Oi u luzi chervona kalyna

"Oi u luzi chervona kalyna" (Ukrainian: «Ой, у лузі червона калина») is a Ukrainian patriotic march. It is translated into English as "Oh, the Red Viburnum in the Meadow". First published in 1875 by the Ukrainian historians Volodymyr Antonovych and Mykhailo Drahomanov, it was arranged by the composer Stepan Charnetsky in 1914, and was used by the Ukrainian Sich Riflemen, the first ethnic Ukrainian military formation of the 20th century, during the First World War. The song has many variations.

The red viburnum (Viburnum opulus) is a national symbol of Ukraine. It is a deciduous shrub that grows 4 to 5 metres (13 to 16 ft) tall. It is depicted as a silhouette along the edges of the flag of the president of Ukraine.

Following the occupation of Crimea in 2014, and then in 2022 the Russian invasion of Ukraine, singing "nationalist anthems" such as "Chervona Kalyna" in Russian-occupied Crimea became punishable by fines and imprisonment.
