A 24-year-old man was stabbed to death in Hell’s Kitchen during a fight that erupted when he stopped to ask a stranger for a cigarette, police said.

The victim was walking with his girlfriend in front of a parking garage on West 42nd Street near Ninth Avenue just after 11 p.m. Tuesday when he spotted a group of three guys and requested a smoke.

The question sparked an argument — that ended with one of the men knifing the victim in the torso, according to cops.

He was rushed to Bellevue Hospital, where he was pronounced dead. 

No arrests have been made. 

The victim, who cops say is from Brooklyn, was not publicly identified pending family notification.
