An elderly man was struck by a stray bullet while sleeping in his Queens nursing home, police said Tuesday.

The near-fatal incident unfolded in Corona around 11:15 p.m. on Saturday night when the 76-year-old woke up bleeding from the right side of his neck and was rushed to Northwell Hospital, according to cops.

The man was treated and sent back to Madison York Assisted Living — but the cause of his injury remained a mystery.

It wasn’t until Monday night when an employee pulled up the blinds in the 76-year-old’s room and found a bullet hole in the window, cops said.

The shooting is the latest in the surging gun violence in New York City.
