A floating oceanic debris collection device may include a circular base, a debris collection unit, and a debris storage unit. The debris collection unit may include a blade erected on an upper surface of the base and an arm extending in an outward direction to a rotation direction side. The debris storage unit may include an annular inner peripheral float installed on a lower surface of the base, an inlet penetrating a peripheral surface of the inner peripheral float, and an outlet penetrating the upper surface of the base. An entirety of the base may be configured to rotate via receiving wind on the sea with the blade. The arm may be configured to scrap debris floating on a sea surface inward. The inlet may be configured to introduce the debris to an inside. The outlet may be configured to facilitate removal of the debris from the debris storage unit.
