- diaphragm (anatomy), a shelf of muscle extending across the bottom of the ribcage of mammals
- diaphragm (contraceptive), a small rubber dome placed in the vagina to wall off the cervix, thus preventing sperm from entering
- diaphragm (mechanics), a sheet of a semi-flexible material anchored at its periphery
- diaphragm seal, a membrane that seals an enclosure
- diaphragm (optics), an opening in the lightpath of a lens or objective that can regulate the amount of light that passes
