The Hollywood Foreign Press, which is behind the Golden Globes, traditionally gives the honor to celebrity offspring.
The 21-year-old said during the annoucement: "I am so grateful to the Hollywood Foreign Press Association for naming me this year's Miss Golden Globe. As a young actress who is just beginning my career, it is truly an honor to be a part of such a special night in film and television."
Other celebrity kids who've been bestowed by the honor include Bruce Willis and Demi Moore's daughter Rumer Willis, Kevin Costner's daughter Lily, and Clint Eastwood's daughter Francesca.
Bacon and Sedgwick also have a son, Travis Sedgwick Bacon, 24.
