Mercedes Helnwein (born 1979, Vienna, Austria) is an artist, writer and filmmaker. Her father is Austro-Irish artist Gottfried Helnwein. She and her brothers, Cyril, Ali, and Wolfgang Amadeus, often modeled for their father's work as children. She grew up in Austria, Germany and the United States and lives now in Ireland and Los Angeles.
Mercedes Helnwein's large-scale drawings, most of which are done with black pencil, colored pencils, or pastels, suggest storyboard or graphic novel frames, although their contents refuse to cohere one picture to another. Helnwein does not so much tell stories or even capture moments in her drawings as she triggers possibilities. Her technical style underscores a sense of displacement.
In an interview with the LA Times Helnwein is quoted as saying: “To be powerful, art should be honest, direct and thought-provoking, It should shake you up, take you out of your element. Making people uneasy is one way to do that.” 
Helnwein's art debuted in 2003, with her first group exhibition hosted in Downtown Los Angeles by art collector and actor Jason Lee. This exhibition was followed by regular self-instigated one-night-shows at spaces throughout L.A., often with photographer Alex Prager with whom she founded Devil's Porchlight Press in 2004. Thereafter, Helnwein began to exhibit in New York, Berlin, Dublin and London.
Mercedes Helnwein contributed art to the Beck album, The Information (2006), and appeared in his music video for "Gamma Ray," filmed by photographer and filmmaker Autumn de Wilde. She has worked with the following galleries: Blackston Gallery (New York), Merry Karnowsky Gallery (Los Angeles), The Shooting Gallery (San Francisco), Pool Gallery, Dittrich & Schlechtriem (Berlin), and Bespoke Gallery (Dublin).
In 2004, her travelogue, "Devil Got Religion," covered the 15-day road trip with Alex Prager and Beth Riesgraf for their "America Motel" installation. In 2006, she signed with the literary agency, Ed Victor Ltd., based in London. Other representation includes the New York agencies, Fletcher & Company and William Clark Associates. Her debut novel, The Potential Hazards of Hester Day, was released in February 2008 by Simon & Schuster.
In 2008, Mercedes Helnwein included video as a medium in her work. Her brother, Ali Helnwein, composed the scores. They continue collaborating as filmmaker and composer. Her short films, "Faking it," “Whistling Past the Graveyard," and "East of Eden," are reminiscent of the strange and mysterious scenes depicted in her drawings.
