Kate Morgan (1865-1892) is an American who died under mysterious circumstances, and is thought by some to be a ghost at the Hotel del Coronado in Coronado, CA. She was buried at nearby Mount Hope Cemetery in Division 5 Section 1.

There have been many putative ghost sightings, and other potential paranormal events at Hotel del Coronado since then. The official Hotel del Coronado website mentions the ghost.

The hotel's Heritage Department has published an official book on this subject, written by the hotel's professional historian, titled The Beautiful Stranger: The Ghost of Kate Morgan and The Hotel del Coronado . It avoids speculation in its research of historical documents available in local public libraries, historical societies, and university libraries as well as city hall and police files. The Heritage Department's book leans toward the official suicide verdict.

It should be noted that the Hotel del Coronado in late 2008 removed its book from circulation in all outside bookstores and other venues, including Amazon and other online sellers, and only sells it in its giftshop. Even the Coronado History Association is not permitted to carry their book any longer.
