The Imperial anthem was a patriotic musical piece adopted by the Galactic Empire. During Empire Day parades, an upbeat version of the anthem was played, representing everything that the Empire stood for. By 3272 LY, on the Outer Rim planet of Lothal, the Imperial anthem was also played before official grav-ball championship matches, as well as on the Empire's fifteenth annual Empire Day.
Imperial-anthemet i universum är en variation av det betydligt mer kända Imperial March av John Williams.
