"Kratt" is an Estonian ballet in four acts by Eduard Tubin. It is considered to be the first Estonian ballet. The libretto is written by Elfriede Saarik. The ballet is entirely based on folk tunes. The premiere was on 31 March 1943 in Vanemuine Theatre. The ballet became infamous in Estonia due to the Soviet "March Bombing" of Tallinn in 1944, when the bombing started as the ballet was being performed at the Estonia Theatre, which was heavily damaged right after the theatre had been evacuated.
