The incident took place in Stamford on Sunday, May 1 at the Boys and Girls Club at 348 Stillwater Ave.
The child was on the swings at the time of the crash and was transported to an area hospital with minor, non-life-threatening injuries, said Sgt. Jeffrey Booth, of the Stamford Police.
The crash took place when a 53-year-old woman driving a four-door sedan hit the gas instead of the brakes and went through a fence and hit the swing set where the boy was swinging, Booth said.
The driver was also transported to a hospital with minor injuries.
The incident is under investigation.
