Kaden Gowers sustained fatal injuries on Fowey Close, in Macclesfield, shortly before 21:00 BST on Tuesday, Cheshire Police said.
He was pronounced dead in the cul-de-sac. Detectives said no-one else is thought to have been involved in the death.
Prayers were held at his school, All Hallows Catholic College.
Principal Tony Billings said: "Kaden Gowers joined All Hallows Catholic College this September, coming into Year 9.
"In a very short space of time he made many new friends both at All Hallows and across the town. We are all deeply saddened by news of the tragic accident which has taken Kaden from us."
A spokesman for Cheshire Police said: "Investigations are ongoing to establish the exact cause of the accident.
"The boy's next of kin have been informed."
A 13-year-old boy run over by what police called an "unattended" car has died.
