Bijou Lily Phillips (b. April 1, 1980, Greenwich, Connecticut, USA) is an American actress, former model, and one-time pop-singer. She is the daughter of John Phillips of The Mamas and the Papas and his then-wife Genevieve Waite, a South African model. The name "Bijou", which is French for "jewel," was taken from the song "My Petit Bijou" by Lambert, Hendricks and Ross.

Phillips, alongside Tara Reid, was chosen of one of the bridesmaids for the Las Vegas wedding of Nicky Hilton. As a direct result of the party-girl personas of these two, the marriage has been greeted with cynicism.
