Police believe the boy was attempting to cross Racecourse Road, near the Banksia Street intersection, when he was struck by an eastbound Mazda Tribute.

The boy was thrown an unknown distance and suffered serious head and chest injuries.

He was rushed to Orange Base Hospital in a critical condition but died overnight during emergency surgery.

It's believed the boy was a student at the nearby Calare Public School.

The 33 year old female driver of the vehicle stopped immediately and is assisting police with their inquiries.

Police from the Canobolas Local Area Command and Chifley Crash Investigation Unit attended the scene to carry out an investigation.

Police are urging witnesses to the accident to contact Orange detectives on 6363 6399 or Crime Stoppers on 1800 33 000.

The child's death is the fourth tragedy to strike Orange in less than a week.

On Wednesday, 19 year-old former Kinross Wolaroi School students Eliza Wannan and Will Dalton-Brown died from injuries sustained from a camping accident near Orange.
