The Prairial is a light monitoring frigate ("frégate de surveillance") of the French Marine Nationale. She is the second ship of her class, and the first French vessel named after the 9th month of the Republican Calendar.

She was built in the beginning of the 1990s by the Chantiers de l'Atlantique in Saint Nazaire. She is currently based in Tahiti.

Although categorised as a surveillance ship, she is rather powerfully armed with four anti-ship Exocet missiles and a 100 mm gun. She is also furbished with 35 extra birth for marines.
