Bogue Sound is a medium-sized geographic sound in the state of North Carolina. The sound is part of North Carolina's "Crystal Coast", a tourism marketing term that is also used interchangeably with the term "Southern Outer Banks." A few small islands in the sound were used for test bombing by airplanes around the time of World War II, and signs at certain points in Bogue Sound warn people of unexploded ordnance. The sound is home to Marine Corps' landing field, Bogue Field.
