Kelly Trump (born 27 August 1970 as Nicole Heyka) is a German pornographic actress.

Trump has performed in story-driven German adult films, such as German Beauty (an adult adaptation of American Beauty), Eiskalte Engel (the German title of Cruel Intentions), the 00Sex series (based on James Bond), and Ariella the Mermaid. She has also acted in a small number of American adult films, including films for Wicked Pictures.

One unusual career move was her involvement in RTL Promiboxen, German TV's version of celebrity boxing. For the 2003 program, she trained as a potential substitute in case the announced boxers, Tanja Szewczenko and Samantha Fox, were unable to participate in their bout. For the 2004 program, Trump was announced as one of the celebrity boxers, with her opponent being Juliane Ziegler, the 22-year-old star of the German TV reality program Der Bachelor. Trump underwent four weeks of intensive training with noted martial arts trainer Klaus Waschkewitz. Trump's ring name was "Bad Babe" while Ziegler's was "Red Rose". On May 1, 2004, Trump stepped into the boxing ring before 1800 spectators at Cologne’s Colleseum, but she was soundly beaten by Ziegler, who easily out-reached and out-pointed Trump to win the three-round bout by a unanimous decision.
