Christopher Haverly (1837–1901), better known as J. H. Haverly or John H. "Jack" Haverly, was an American theatre manager and promoter of blackface minstrel shows. During the 1870s and 1880s, he created an entertainment empire centered on his minstrel troupes, particularly Haverly's United Mastodon Minstrels and Haverly's Colored Minstrels. Under his guidance, these troupes grew to impressive sizes and featured elaborate sets and costumes. They toured widely, enlarging minstrelsy's audience to encompass the entire United States as well as England. Haverly's methods sparked a revolution in minstrelsy as other troupes scrambled to compete. As the costs of minstrelsy increased, many troupes went out of business.
