Nadja Auermann (born 19 March 1971) is a German model and actress. Fashion designer Valentino once commented on her physical resemblance to Marlene Dietrich. A New York Times fashion columnist, Guy Trebay, wrote of her "ice maiden visage and pole vaulter's legs". She once held the record for being the model with the longest legs in the world in the Guinness Book of Records.
In 1989, Auermann was discovered in a cafe in Berlin, which led her to sign with Karin Modeling Agency in Paris in the same year. In 1991, she moved from Karin to Elite Model Management. She then had her picture taken for Vogue Paris, in addition to appearing in Benetton clothing advertisements. In September 1994, Auermann appeared on the cover of both Vogue and Harper's Bazaar, which The New York Times called "a triumph akin to winning two legs of the Triple Crown of Thoroughbred Racing".
She has walked the runways for Chloé, Givenchy, Salvatore Ferragamo, Louis Vuitton, Valentino, Chanel, Hermès, Dolce & Gabbana, Viktor & Rolf, Prada, Jean Paul Gaultier, Versace, Giles Deacon, Vivienne Westwood, Gianfranco Ferré, Fendi, Jil Sander, Christian Dior, and Yves Saint Laurent.
