The man was crossing the junction between Alexandra Road and Newland Avenue when he was hit by a white Kia car.
He was taken to Hull Royal Infirmary for treatment to minor injuries after the accident at 4.30pm on Wednesday.
The driver of the car stopped briefly, but drove away without leaving any details.
