Drum Inlet and Ophelia Inlet are inlets of the Outer Banks in the U.S. state of North Carolina. They connect the Core Sound with the Atlantic Ocean and separate North Core Banks from South Core Banks. The exact inlet locations and names have changed with time, as new inlets open, merge, or close. Conversationally, the inlet or inlets between mile 19 and 23, as measured from Ocracoke Inlet, are typically called Drum Inlet even when, geologically, they have other names.
