A manual breast pump adapted for one-handed operation includes a pump body defining an inlet, an outlet and a vacuum port, a stationary handle connected to the pump body, and a movable handle connected to the manual breast pump and spaced from the stationary handle so that both handles can be grasped simultaneously between the palm and fingers of a hand. The movable handle is movable with respect to the stationary handle and is operably connected to a piston disposed within the pumping chamber so that movement of the movable handle with respect to the stationary handle results in movement of the piston within the pumping chamber to create a vacuum at the vacuum port. The invention provides a manual breast pump which can be easily and comfortably supported and operated using one hand.
