Fire breather's pneumonia, also known as fire breather's lung or fire-eater's lung, is a distinct type of exogenous—that is, originating outside the body—lipoid pneumonia (chemical pneumonitis) that results from inhalation or aspiration of hydrocarbons of different types, such as lamp oil. Accidental inhalation of hydrocarbon fuels can occur during fire breathing, fire eating, or other fire performance, and may lead to pneumonitis.

Symptoms can vary significantly among individuals, ranging from asymptomatic to a severe, life-threatening disease. Onset usually occurs within hours, though symptoms may not appear for several days. Lipoid pneumonia is a rare condition, but is an occupational hazard of fire performers.

Fire breather’s pneumonia is caused by the entrance of hydrocarbon fuels into the bronchial tree, usually due to accidental aspiration or inhalation during a fire performance show. Fire breathing, or fire blowing, is the act of creating a plume of fire by blowing a mouthful of fuel in a fine mist (atomization) over a source of ignition. Fire eating, or fire swallowing, is the act of putting a flaming object into the mouth and extinguishing it.

In both disciplines, the performer holds their breath until the air is clear of vapors, so as to not inhale the hazardous fumes. However, improper technique or an accident can lead to ingestion, inhalation, or aspiration of fine droplets or vapors. Fire breathing and fire eating are separate acts, but the terms are sometimes erroneously used interchangeably in the literature.
