Bengawan Solo (song)

"Bengawan Solo" (lit. 'the great river of Solo') is an Indonesian Kroncong-style song written by a Javanese, Gesang Martohartono, in 1940. The song is a description of the longest river in the Indonesian island of Java, the Solo River. The song became popular in Indonesia (and Asia as a whole) during the Second World War and was one of the songs promoted nationally in the newly-independent country after the war.

The song is the first song written by an Indonesian in the Indonesian language to achieve widespread popularity in Indonesia. It also became popular in Japan, other Far East and Southeast Asian countries, and many versions of the song in different languages exist.

In October 2025, "Bengawan Solo" was recognized as a National Intangible Cultural Heritage of Indonesia by the Ministry of Culture of the Republic of Indonesia.
