A man was stabbed during a fight inside the Target store in Herald Square Monday afternoon, cops said.

The 33-year-old victim was knifed in the armpit inside the store on West 34th Street near Sixth Avenue just after 2 p.m., police said.

The attack stemmed from a feud with another man, who took off after the stabbing, authorities said.

The victim was taken to Bellevue Hospital, where he was listed in stable condition, cops said.

It appeared that neither the victim nor the suspect worked at the store.

The nature of the dispute was not immediately known.
