A woman was punched in the face in a random Midtown attack, cops said Tuesday.

The unknown attacker said nothing to the 20-year-old stranger before hitting her just after 5 p.m. Aug. 20 at the corner of Seventh Avenue and 52nd Street, according to police.

The assailant took off and the woman was treated at Bellevue Hospital for a cut to her lip, police said.

The NYPD released a photo of the suspect Tuesday.
