Two people were slashed in the Big Apple Saturday — including a tourist from Michigan who ignored a stranger’s catcalls, cops said.

The 23-year-old visitor was walking with a friend on West 46th Street near Eighth Avenue around 4:30 a.m. Saturday when a stranger started hitting on her, authorities said.

The friend told the man to stop — but instead of ending his antics, he followed the tourist and sliced her on her chest and right hand, cops said.

The woman refused medical attention on the scene but received medical care privately at a later time.

The suspect, who fled, remains at large.

Hours later, a 31-year-old man was on a southbound 2 train approaching the 149th Street station in Mott Haven around 11 a.m. when another man approached and snarled, “Keep talking, b—h,” authorities said.

The suspect then pulled out an unspecified “cutting instrument” and slashed the victim in the neck, police said.

He was taken to a local hospital, where he received 16 stitches, cops said.

That slasher also remains on the loose.
