A man punched a 75-year-old woman in the face in an unprovoked attack as she got off a Queens bus, cops said early Thursday.

The elderly victim had just stepped off a Q36 bus at Hillside Avenue and Edgerton Boulevard in Jamaica Estates around 1:30 p.m. Saturday when a stranger approached and punched her in the forehead without saying a word, cops said. 

The victim was taken to an area hospital, where she was treated and released.

The suspect, who fled, is about 5 feet 6 with a medium build. He was last seen wearing a white surgical mask, an orange du-rag, a black hooded jacket, multi-colored pants, orange and black sneakers, and carrying an orange and gray backpack.

He is shown in surveillance video inside a nearby store.
