Dr. Elizabeth Fishman Loftus (born October 16, 1944) is an American psychologist who is best known in relation to the misinformation effect, false memory and criticism of recovered memory therapies.

Her research includes the effects of phrasing on the perceptions of automobile crashes, the "lost in the mall" technique and the manipulation of food preferences through the use of false memories. In the Jane Doe case that began in 1997, Loftus and Melvin J. Guyer revealed serious concerns about the background and validity of the initial research. She has also served on the executive council of the Committee for Skeptical Inquiry and was a keynote speaker at the British Psychological Society's 2011 annual conference.

As well as her scientific work, she has provided expert testimony or consultation for lawyers in over 300 court cases, including for the legal teams of Ghislaine Maxwell, Harvey Weinstein, Ted Bundy, O.J. Simpson, Angelo Buono, and Robert Durst. She has also written many books, including The Myth of Repressed Memory: False Memories & Allegations of Sexual Abuse and Witness for the Defense.
