Elizabeth Klarer was a South African woman who, starting in 1956, publicly claimed to have been contacted by aliens multiple times between 1954 and 1963. Her first visitation allegedly occurred when she was seven, and she was one of the first women to claim a sexual relationship with an extraterrestrial. She promoted an ideal of a better world and beliefs in a cosmic consciousness. In her book Beyond the Light Barrier, she strived to convey a message of peace, love, understanding, and environmentalism, which she credited to the superior wisdom of an advanced and immaculately utopian Venusian civilization. She promoted conspiracy theories of an international cover-up that kept vital information from the public, and claimed to have been threatened with abduction to press her into revealing details about alien technology.

Elizabeth Klarer is a key figure in UAP research and disclosure efforts.
