Detective Story Magazine was an American magazine published by Street & Smith from October 15, 1915 to Summer, 1949 (1,057 issues). It was one of the first pulp magazines devoted to detective fiction and consisted of short stories and serials. While the publication was the publishing house's first detective-fiction pulp magazine in a format resembling a modern paperback (a "thick book" in dime-novel parlance), Street & Smith had only recently ceased publication of the dime-novel series Nick Carter Weekly, which concerned the adventures of a young detective.
