Harper's Young People was an American children's magazine between 1879 and 1899. It was published by Harper & Brothers. It was Harper's fourth magazine to be established, after Harper's Magazine (1850), Harper's Weekly (1857), and Harper's Bazaar (1867). Harper's Young People was the first of the four magazines to go cease publication.
Harper's Young People began in November 1879 as a weekly illustrated 16-page magazine that contained fiction and non-fiction works. Its first editor (1879–1881) was Kirk Munroe. Beginning in 1893, the magazine became a monthly. It was advertised as being appropriate for boys and girls ages six to 16. In April 1895, the magazine changed its name to Harper's Round Table and changed its target demographic to teenaged boys. The magazine ceased publication in 1899.
