Disclosed are substrate polishing apparatuses, substrate polishing systems, and/or substrate polishing methods. The substrate polishing apparatus may include an electric field applying module, and a platen that rotates a polishing pad. The electric field applying module may include an inner electrode having a circular shape when viewed in plan. The platen may be on the inner electrode. A central axis of the inner electrode may be spaced apart from a central axis of the platen. The inner electrode may include a first electrode and a second electrode that may surround the first electrode and may have an annular shape.
