The present disclosure provides an optical element driving mechanism, which includes a movable part, a fixed assembly, and a driving assembly. The movable part is configured to be connected to an optical element. The fixed assembly has a first opening, and the movable part is movable relative to the fixed assembly along a first axis. The driving assembly is configured to drive the movable part to move between a first position and a second position relative to the fixed assembly, so that the optical element selectively overlaps the first opening.
