A pivoting wheelchair backpack holder is provided. The pivoting wheelchair backpack includes a lever rod and a swing-out handle to move the lever rod, a frame moved by the lever rod, and a backpack attached to the frame. In its closed position, the backpack rests behind the user sitting in the wheelchair with the handle positioned flush to the side of the wheelchair. The user grabs the handle from its resting position, locks the handle into place against the lever rod, and pulls the handle to move the lever rod. The lever rod opens the frame, which then moves from the back of the wheelchair to the side of the wheelchair. A second hinged joint between the lever rod and frame allows the user to pull the backpack down toward the user. The user can access the backpack now at his or her side. The user can close the frame by pushing the frame back up, moving the handle in the opposite direction and replacing the handle to its resting position.
