A Thames Valley Police spokeswoman appealed for any witnesses and anyone who has dashcam footage to get in touch with officers investigating the case.
She said: "At 8.26pm on Saturday the girl was walking in Buckingham Road, Aylesbury, when she was involved in a collision with a black car, possibly with four doors, on a zebra crossing outside the Royal Buckinghamshire Hospital at the triple roundabouts.
"The vehicle was travelling northbound. The driver did not stop at the scene.
"The girl was treated at Stoke Mandeville Hospital in Aylesbury, but has since been discharged."
