Marie Pierre Louis de Frotté (August 1, 1766 – February 18, 1800) was a French soldier and an opponent of the Republic during the Revolutionary Wars.

Frotté joined the émigrés, and served in the combined Prussian and Austrian army of the Duke of Brunswick, which aimed to restore the monarchy in France.

Returning to England, he was enlisted by Charles, Count of Artois (Louis XVI's younger brother), in an attempt to start yet another rebellion in his native Normandy.

This rebellion was fairly successful, but, after Napoleon Bonaparte seized power, the tide began to turn against Frotté, as most of his direct subordinates were killed.

When, in early 1800, many rebel soldiers deserted, he began to negotiate with the government, eventually being invited by General Guidal to a meeting in Alençon.
