Strictly, the expression face mask is tautological and means "mask", because masks by definition go on the face; but it is sometimes used to mean:
- Surgical mask
- Respirator
- Among divers, diving mask
- Face mask (gridiron football), the metal grid face protecter on his helmet, and the penalizable foul of grasping it during play
