The assault happened in the Carnagh Park area of the city just before 3am on Thursday.
Northern Ireland Ambulance Service attended the scene.
Another 57-year-old man, arrested on suspicion of attempted murder, was also stabbed in the leg.
His injuries were described by police as not life-threatening.
SDLP councillor for the area, Kevin McAteer told UTV: "I can't comprehend why someone would stab somebody - it's disgusting.
"It's not the kind of image we want to portray to our young people.
"We don't want people thinking, that to resolve a situation, they have to brandish a knife."
