Police charged two young men in a stabbing in Manhattan Wednesday night, cops said.

Witnesses said Victoriamo Florez, 19, and Lenel Ramirez, 21, approached three men at the west end of Pier 84 near 44th Street and 12th Avenue about 8:30 p.m. , cops said.

The victims recognized them from the Covenant Houses, a homeless youth shelter on 41st Street where both the suspects and victims live, and a fight broke out, according to a police source.

An 18-year-old and a 22-year-old were stabbed, and treated at Bellevue Hospital for their injuries, which were not life-threatening.

Another man was slashed in the shoulder, but did not need medical treatment.

Police took Florez and Ramirez into custody, and they were charged with assault and criminal possession of a weapon.

A knife was recovered at the scene.
