Pierre-Gustave Roze (28 November 1812 – November 1883) was a French admiral.
He was born in Toulon, France and throughout his adult life served as a career naval officer.
As a young rear admiral (contre-amiral) he served in Mexico during the French intervention there of 1862.
In 1865 he was appointed commander of the French Far Eastern Station (Station des mers de Chine).
As commander, he was primarily stationed in Yokohama, headquarters of the French Far Eastern Squadron, though he was involved in naval operations in nearby Korea and French Indochina in 1866.
He won most recognition during the French Campaign against Korea in 1866, an offensive involving the French Far Eastern Squadron as well as French marines that proved a failed attempt to force reparations from the Korean court for its persecution of French and native Catholics.
After the Korean expedition Roze and his fleet returned to Japan, where they were able to welcome the first French military mission to Japan (1867–1868) in Yokohama harbor on January 13, 1867.
