A man was viciously stabbed Monday night during an apparent mugging near Riverside Park in Manhattan, cops said.

The 44-year-old man was confronted by up to five male strangers dressed in hooded sweatshirts around 7:50 p.m. near West 138th St. and Riverside Drive in West Harlem, and then stabbed in the stomach and chest, police sources said.

EMS rushed the victim to St. Luke’s Hospital, where he was in stable condition.

The men fled on foot and are being sought, police said.

It was not immediately clear if anything was taken from the victim, cops said.
