Pierre Ozanne was a French naval artist and engineer, brother of Nicolas Ozanne.

From 1750, Ozanne was schooled at the Ecole des Gardes de la Marine, ancestor of the École Navale, and in Paris, where he was a pupil of Duhamel du Monceau. He returned to Brest in 1764 with a commission of drawing professor at the naval academy.

From 1771 to 1772, he took part in a scientific expedition on the frigate Flore, and in 1776, on the Boussole.

After the start of the American war of Independence, Ozanne served on Languedoc and on the Vautour.

In 1788, he directed the plans of the 74-gun Vengeur, earning a commission of naval engineer in the process.

Ozanne contributed to the propaganda of the Revolutionary era by commissioning two notable works: le Vengeur du Peuple au combat de prairial, in 1795, depicting the highly romanticised tale of the sinking of the French ship Vengeur du Peuple; and Le combat de la Bayonnaise, in
