Dorothy Louise Eady, also known as Omm Sety or Om Seti (16 January 1904 – 21 April 1981), was keeper of the Abydos Temple of Seti I and draughtswoman for the Department of Egyptian Antiquities.
She is especially well known for her belief that in a previous life she had been a priestess in ancient Egypt, as well as her considerable historical research at Abydos.
Her life and work has been the subject of many articles, television documentaries, and biographies.
A 1979 New York Times article described her life story as "one of the Western World's most intriguing and convincing modern case histories of reincarnation".
