The "Himno Nacional de Uruguay" (English: "National Anthem of Uruguay"), also known by its incipit "Orientales, la Patria o la Tumba" (English: "Easterners, the Country or the Tomb"), is the longest national anthem in terms of duration with 105 bars of music (about four-and-a-half to six minutes), though an abridged version is performed on most occasions.

Its lyrics are by Francisco Acuña de Figueroa, who was also author of the lyrics to Paraguay's national anthem; "Paraguayos, República o Muerte". The lyrics were officially declared the national anthem on July 8, 1833, while the current musical composition was declared as the official by law on July 25 and 26, in 1848.
