Respiration may refer to:

## Biology

* Cellular respiration, the process in which nutrients are converted into useful energy in a cell
   * Anaerobic respiration, cellular respiration without oxygen
   * Maintenance respiration, the amount of cellular respiration required for an organism to maintain itself in a constant state
* Respiration (physiology), transporting oxygen and carbon dioxide between cells and the external environment
   * Respiratory system, the anatomical system of an organism used for respiration
   * Breathing, passing air in and out through respiratory organs
   * Aquatic respiration, animals extracting oxygen from water
   * Artificial respiration, the act of simulating respiration, which provides for the overall exchange of gases in the body by pulmonary ventilation, external respiration and internal respiration
   * Cheyne–Stokes respiration, an abnormal pattern of breathing characterized by progressively deeper and sometimes faster breathing, followed by a gradual decrease that results in a temporary stop in breathing called an apnea
* Respiration, a journal by Karger Publishers

## Ecology

* Carbon respiration, a concept used in calculating carbon (as $CO_2)$ flux occurring in the atmosphere
* Ecosystem respiration, measurement of gross carbon dioxide production by all organisms in an ecosystem
* Root respiration, exchange of gases between plant roots and the atmosphere
* Photorespiration, enzymatic combination of RuBP with oxygen

## Entertainment

* "Respiration" (song), a 1999 single by Black Star
* "Respire" (song), a 2003 song by Mickey 3D
