Helen Reimensnyder Martin (1868–1939) was an American author.
 She was born in Lancaster, Pennsylvania, studied at Swarthmore and at Radcliffe colleges; and married Frederic C. Martin in 1889.
 She became known for her stories of "the Pennsylvania Dutch," the shorter ones contributed to "Leslie's", the "Century", the "Cosmopolitan", the "Ladies' Home Journal", and other magazines.
 Her early work was so harshly photographic and sensational that it was quite naturally resented by the people whom she portrayed.
 Her well-known novel "Tillie: a Mennonite Maid" (1904) especially provoked many cries of misrepresentation.
 The story, about a young girl of Pennsylvania Dutch, but not Mennonite, background, though she briefly joins a Reformed Mennonite church in her teens, chronicles the early life of a girl who eventually becomes a school teacher, attends college, and marries, escaping the domination of her harsh father.
