Two men who apparently OD’d were found dead on a bench on the Coney Island boardwalk Monday morning, cops and a police source said.

The men, who appeared to be in their forties, were found unresponsive on the Riegelmann Boardwalk between West 15th Street and West 16th Street around 8 a.m. They were pronounced dead at the scene.

The city Office of the Chief Medical Examiner will determine the cause of death, police said.

“It’s believed to be a drug overdose,” a police source said.
