Elettra-Ingrid Rossellini Wiedemann (born July 26, 1983) is an American food editor, writer, fashion model, and socialite.

Growing up, Wiedemann suffered from scoliosis, a spinal condition that had also afflicted her mother, and had to wear a back brace 23 hours a day from the ages of 12 to 17.

She was discovered by Bruce Weber and quickly became one of the industry's most coveted models, shooting with photographers such as Karl Lagerfeld, Patrick Demarchelier, Annie Leibovitz, Arthur Elgort, Mario Testino, and Craig McDean for magazines such as American Vogue, French Vogue, Harpers Bazaar, Another, Muse, GQ, the French and Italian editions of Elle, to name a few.

Her MSc dissertation was an analysis of a biotech proposal known as Vertical Farming and the future of feeding urban populations in light of climate change.

She has also written for publications including Refinery29, VICE Munchies, Teen Vogue, SELF, Paper Magazine, The Cut, and Cherry Bombe.
