I Know Who Killed Me is a 2007 thriller film directed by Chris Sivertson and starring Lindsay Lohan. Filming began on December 16, 2006 and finished in late February 2007. It was released on July 27, 2007.

Aubrey Fleming, a successful and well-liked college student, vanishes without a trace. Two weeks after her disappearance, Aubrey reappears just as mysteriously, being found unconscious in the woods. When the traumatized young woman reawakens in the hospital, she tells a horrifying story - Aubrey was kidnapped, and tortured. However, the woman in the hospital claims that she is not Aubrey Fleming, and that the real Aubrey Fleming is still in grave danger. The woman identifies herself as an exotic dancer named Dakota Moss - claiming that the fact that her appearance is identical to Aubrey's is a bizarre coincidence (Dakota Moss is, in fact, the main character in a story that Aubrey wrote for a class). Aubrey's family and doctors try to figure out whether the young woman is Aubrey and suffering from a dissociative disorder because of her ordeal or whether she is in fact, another woman entirely.

No preview screenings were arranged for film reviewers. The day after the film opened, RottenTomatoes.com showed a 8% rating with the consensus statement: "Distasteful and ludicrously plotted". It currently holds an 18% rating on Metacritic, which indicates "extreme dislike or disgust."

One reviewer wrote, "Much like the career of its star, I Know Who Killed Me opens promisingly, starts to stumble in the middle and has gotten so laughably ridiculous by the final act that you can't take it seriously at all."

The film was a box office failure, and opened at #9 on opening weekend, with $3.4 million dollars.
