Liliane Rudabet Gloria Elsveta Sobieski (born June 10, 1982), known professionally as Leelee Sobieski, is an American actress. Sobieski achieved recognition in her mid-teens for her performance in the 1998 film Deep Impact. She received an Emmy nomination for the 1999 TV movie Joan of Arc, and two Golden Globe nominations for Joan of Arc and the 2001 TV movie Uprising.
Sobieski was born in New York City. Her parents are American novelist/screenwriter Elizabeth (née Salomon), who also works as Sobieski's manager, and French painter and former actor Jean Sobieski. Sobieski has a younger brother, Robert.
Sobieski's first name, "Liliane", was the name of her paternal grandmother. One of her middle names, "Elsveta", is derived from "Elżbieta", which is the Polish equivalent of "Elizabeth". Her father is of Polish and Swiss ancestry. Her maternal grandfather, United States Navy captain Robert Salomon, was Jewish, and Sobieski grew up in a "pan-religious" family; she has said that she is "proud of Jewish roots". She attended Trevor Day School and studied literature and fine art at Brown University.
