The teenager suffered fatal injuries during the clash on Henbury Street, a residential road between Rusholme and Moss Side.
The emergency services, including the police helicopter, flooded to the scene following the first reports of a stabbing at 7.30pm on Sunday.
The 17-year-old boy had suffered a fatal stab injury and died at the scene.
Three others were taken to hospital with stab injuries although their conditions are not thought to be life-threatening.
Police have launched a murder investigation.
A boy of 17 was arrested at the scene - he remains in custody and will be questioned by detectives in connection with the death.
