76 (TH 36) (Russian: Гроза, groza), is an overture (in the context of a symphonic poem) in E minor composed by Pyotr Ilyich Tchaikovsky around June and August 1864.

He was spending the summer at the family estate of Prince Aleksey Vasilievich Golitsyn at Trostinets, near Kharkov in Ukraine, and wrote the overture as a vacation exercise.

This opinion may have been influenced by Anton Rubinstein, who disapproved of it, and by Herman Laroche, who said it represented "a museum of antimusical curiosities".

The Storm was first performed, posthumously, in Saint Petersburg on March 7, 1896, conducted by Alexander Glazunov.

The "Poco Meno Mosso" section of the piece is also used as the main theme for the second movement of his Symphony No.
