Ah Ken (fl. 1858–1896), also known as Ah Kam, was a Chinese American businessman and popular figure in Chinatown, Manhattan during the mid-to late 19th century. The first Asian man to permanently immigrate to Chinatown, although Quimbo Appo is claimed to have arrived in the area during the 1840s, Ah Ken resided on Mott Street and eventually founded a successful cigar store on Park Row.
