An optical member driving mechanism for driving an optical member is provided, including a fixed portion, a movable portion, and a driving module. The movable portion can support the aforementioned optical member, and the driving module can drive the movable portion to rotate relative to the fixed portion around a rotating axis, wherein the rotating axis is different from the optical axis of the optical member. The driving module includes a first electromagnetic driving assembly and a second electromagnetic driving assembly, and the optical axis is disposed therebetween. The first electromagnetic driving assembly and the second electromagnetic driving assembly are disposed on a side of the movable portion, and are electrically independent.
