Emma Hardinge Britten (2 May 1823 – 2 October 1899) was an English advocate for the early Modern Spiritualist Movement. Much of her life and work was recorded and published in her speeches and writing and an incomplete autobiography edited by her sister. She is remembered as a writer, orator, trance clairvoyant, and spirit medium. Her books, Modern American Spiritualism (1870) and Nineteenth Century Miracles (1884), are detailed accounts of spiritualism in America.
