A man is clinging to life after a brutal group beatdown caught on tape outside a Bronx bar, according to cops.

The fight began when the victim, 36, knocked a woman to the sidewalk in front of Parrila Latina on Broadway around 4:15 a.m. Monday, police sources said.

It’s not known whether the shove was accidental.

One of the woman’s angry companions can be seen on security footage slugging the man in the face, after which a crowd quickly surrounds him, kicking and punching.

The barrage quickly knocked him unconscious, leaving him with a severe head injury. He remains at St. Barnabas hospital in critical condition, authorities said.

Cops are looking for everyone involved in the fracas, particularly the assailant in a baseball cap who threw the first punch. No arrests have been made.
