Ellen Rocche (born July 19, 1979, also known as Ellen Roche) is a Brazilian actress and model. She began her career on the Sunday TV program Qual é a música? (literally, "What`s the music?") with Silvio Santos on the Brazilian channel SBT. She has also acted in some chapters of the Globo program Zorra Total.

Appreciated mainly for her physical attributes, namely her hips, buttocks and slim waist, she would gain national exposure again when she joined the cast of a reality show based loosely on the Dutch Big Brother, dubbed Casa dos Artistas, in which famous people ("B" celebrities, in lieu of the usual anonymous participants) were locked together in a house and then gradually voted out. This led SBT to steal rating points from Globo - the latter owned the copyrights for Big Brother Brazilian edition and was secretly preparing the first one when Casa do Artistas started.

It was on Casa dos Artistas that Ellen met her current fiancé, Brazilian actor Ricardo Macchi. The couple started dating while locked in the house and got engaged on 2007, on Bariloche, Argentina.

Ellen Roche was also featured on the Dream Girl Cam, for the Venice Online website and played a Brazilian version of the Lara Croft character, to promote the movie Tomb Raider in Brazil.
