The invention belongs to the technical field of underwater propellers, and particularly relates to a backpack ducted underwater propeller. The underwater propeller comprises a ducted propeller body, a propelling power part and a motion control part, wherein the ducted propeller body comprises an outer shell, an inner shell and a bottom plate, and the tail end of the bottom plate is used for connecting the inner shell and the outer shell; the outer shell, the inner shell and the bottom plate define a ducted cylindrical structure; the interior of the ducted cylindrical structure is through, and water passes through the ducted cylindrical structure; the propelling power part comprises a power supply system, a propelling motor and paddles; the motion control part comprises a control handle and a control system; and the control system is used for controlling the propulsion motor to rotate according to a signal sent by the control handle so as to control the motion of the underwater propeller. The backpack type underwater propeller provided by the invention can be fixed on the back no matter on land or under water, and does not need to be held by hands, so that the operation space of both hands is released as much as possible, a user can conveniently focus on diving operation, and the operation efficiency is improved.
