A 5-year-old girl was grazed by a stray bullet when she was caught in the middle of a gun fight between two warring gangs on a Bronx street Wednesday evening, according to cops and sources.

The child was grazed in the ear when shots were exchanged between two crews, believed to be gang-affiliated, on Southern Avenue in Longwood around 5:40 p.m., the NYPD and sources said.

The youngster was an unintended target in the broad daylight shootout — which sent panicked residents scattering for shelter, the sources added.

She was taken to Harlem Hospital in stable condition, cops said.

No arrests have been made, and the investigation remains ongoing.
