A woman was fatally stabbed early Tuesday in Brooklyn — and cops are looking for a female suspect who they believe attacked her.

The 37-year-old victim, who was not immediately identified pending family notification, was discovered with multiple stab wounds on Pitkin Avenue near Osborn Avenue in Brownsville around 3:15 a.m., police said.

She was rushed to Kings County Hospital Center, where she was pronounced dead.

The victim appeared to be trying to break up a dispute when her attacker approached her from behind, police sources said.

Police believe a female suspect fled the scene before officers arrived.
