In dance, the galop, named after the fastest running gait of a horse (see gallop), a shortened version of the original term galoppade, is a lively country dance, introduced in the late 1820s to Parisian society by the Duchesse de Berry and popular in Vienna, Berlin and London. In the same closed position familiar in the waltz, the step combined a glissade with a chassé on alternate feet, ordinarily in a fast 2/4 time. The galop was a forerunner of the polka, which was introduced in Prague ballrooms in the 1830s and made fashionable in Paris when Raab, a dancing teacher of Prague, danced the polka at the Odéon Theatre, 1840. In Australian bush dance, the dance is often called galopede.

The galop was particularly popular as the final dance of the evening. The "Post horn Galop" written by the cornet virtuoso Herman Koenig was first performed in London, 1844; it remains a signal that the dancing at a hunt ball or wedding reception is ended.

Perhaps the most famous galop today is the concluding one in the overture to Rossini's opera Guillaume Tell, known popularly as the Lone Ranger theme.^{[citation needed]}
