Cavity may refer to:
Biology and healthcare

Body cavity
A body cavity is any space or compartment, or potential space, in an animal body. Cavities accommodate organs and other structures; cavities as potential spaces contain fluid.
The two largest human body cavities are the ventral body cavity, a ...
, a fluid-filled space in many animals where organs typically develop
**
Gastrovascular cavity, the primary organ of digestion and circulation in cnidarians and flatworms
*
Dental cavity or tooth decay, damage to the structure of a tooth
*
Lung cavity, an air-filled space within the lung
*
Nasal cavity
The nasal cavity is a large, air-filled space above and behind the nose in the middle of the face. The nasal septum divides the cavity into two cavities, also known as fossae. Each cavity is the continuation of one of the two nostrils. The nas ...

Microwave cavity
A microwave cavity or radio frequency cavity (RF cavity) is a special type of resonator, consisting of a closed (or largely closed) metal structure that confines electromagnetic fields in the microwave or radio frequency, RF region of the spect ...
or ''RF cavity'', a cavity resonator in the radio frequency range, for example used in particle accelerators
*
Optical cavity
An optical cavity, resonating cavity or optical resonator is an arrangement of mirrors or other optical elements that confines light waves similarly to how a cavity resonator confines microwaves. Optical cavities are a major component of lasers, ...

Cavitation
Cavitation in fluid mechanics and engineering normally is the phenomenon in which the static pressure of a liquid reduces to below the liquid's vapor pressure, leading to the formation of small vapor-filled cavities in the liquid. When sub ...
, the phenomenon of partial vacuums forming in fluid, for example, in propellers
