Bronchial asthma is a chronic airway inflammatory disease with complex pathophysiological characteristics. Autophagy is involved in the normal physiological activities and metabolism of cells by degrading damaged organelles，proteins and invading pathogenic microorganisms. It is closely related to the survival and development of cells，and has been confirmed to be associated with the development of many diseases including asthma，which is a hotspot of current research. This review will summarize and evaluate the progress of study of the relationship between autophagy and asthma.
