A woman stabbed a stranger on the head with her high heel shoe when a squabble on a subway car turned violent, cops said.

The straphangers were on a Queens-bound F train at the Delancey Street station around 4:55 a.m. Friday when the fight broke out.

The furious woman ripped off her shoe and stabbed the heel into the left side of the 26-year-old man’s scalp, police said.

The woman was last seen running off towards the Williamsburg Bridge.

The victim was taken to Bellevue Hospital, where he received several staples in his head.
