The Chambelona War, or the Chambelona Revolution, was an armed conflict in Cuba in 1917, triggered by a dispute over the legitimacy of the 1916 presidential elections. The war was fought primarily between the Liberal Party, which alleged electoral fraud, and the Conservative government of President Mario García Menocal. The conflict derived its name from the popular song La Chambelona, which became an anthem for the Liberal rebels. The war occurred within the broader context of the Sugar Intervention, and U.S. political and economic influence in Cuba following the Platt Amendment, which granted the United States the right to intervene in Cuban affairs. The Chambelona War was contained mostly to the Eastern provinces of Cuba, and did not touch provinces in the West of Cuba.
