The Voltigeurs were French military skirmish units created in 1804 by Emperor Napoleon I. They replaced the second company of fusiliers in each existing infantry battalion. The voltigeurs moniker later saw use with other militaries.

Voltigeurs (English: "vaulters") were named after their originally conceived mode of operation: although they were foot soldiers, on the battlefield they were intended to jump onto the croup of cavalry horses to advance more quickly. This proved unworkable and they were trained to be elite skirmishers, but they retained their original name. Voltigeurs formed an integral part of the Grande Armée's basic building blocks, the line and light infantry battalions.

In 1804, each French Line (Ligne) and Light (Légère) infantry battalion was ordered to create one company of ninety of the best shots who would serve as elite skirmishers. The voltigeurs were skilled at sharpshooting and received specific training in marksmanship, using cover and taking the initiative.

Like the grenadiers, this company would frequently be detached from the battalion to perform specialised light infantry tasks—operating in loose formation, forming the skirmish line and screening the battalion from the enemy. The formation instruction for voltigeurs gave no indication where they were supposed to stand in the battle line.

Although the original concept of skirmishers using cavalry to transport them during battle quickly proved unworkable in any large scale, voltigeurs did on occasion ride with French dragoons to battle, as recalled by a British officer on the harrowing retreat of John Moore's army prior to the Battle of Corunna.

The French had much the advantage of us in these petty warfares, for I have frequently seen their light troops mounted behind their dragoons, so that when they came to a favourable place to make an attack, these fellows dismounted quite fresh, and our light troops who had been always marching, had to oppose them; still we managed to beat them off.

With the reorganization of 1807 the voltigeur company was enlarged to 121 men. When the battalion was formed up in line formation, the voltigeurs took their place on the left of the line, the second most prestigious position. The top position, the right, was occupied by the battalion's grenadier company.

The French voltigeurs suffered huge losses during the 1812 Russian campaign. One account described how they were decimated by the combined forces of Russian artillery and cuirassiers after bearing the brunt of cavalry charges. After this period, the quality of the French voltigeurs declined as the new units lacked the experience and training to set them apart from their "non-elite" compatriots in the regular light infantry chasseur companies. The hastily reformed regiments of 1813, numbering up to 19, were not up to the same standard as the elite units of the Voltigeurs before the Russian campaign. Despite this, the Voltigeurs of the Guard performed admirably in the 1813–1814 campaigns.
