Charles H. Duprez (14 March 1833 – August 31, 1902) was an American minstrel show performer and manager.

Duprez was originally from France, according to his naturalization record on 29 July 1887 Lowell, Massachusetts and began performing minstrel shows in 1852 in New Orleans, with a group that became known as Carle, Duprez and Green's Minstrels.

His effort to revive the hotel's fortunes were unsuccessful, but he continued to work in different capacities in the area's hotel business and operating rides at local amusement parks.

Shortly before he died, he was running the "boat merry-go-round" at Crescent Park in Providence.

1902 obituary reports stated that he was 65 years old at the time of his death, but Edward Le Roy Rice's 1911 Monarchs of Minstrelsy reports that Duprez was born in Paris, France on March 13, 1830.
