Qigong (/ˈtʃiːˈɡɒŋ/) is a holistic system of coordinated body-posture and movement, breathing, and meditation used for the purposes of health, spirituality, and martial-arts training. With roots in Chinese medicine, philosophy, and martial arts, qigong is traditionally viewed by the Chinese and throughout Asia as a practice to cultivate and balance qi (pronounced approximately as "chi"), translated as "life energy".

Qigong practice typically involves moving meditation, coordinating slow-flowing movement, deep rhythmic breathing, and a calm meditative state of mind. People practice qigong throughout China and worldwide for recreation, exercise, relaxation, preventive medicine, self-healing, alternative medicine, meditation, self-cultivation, and training for martial arts.

Researchers have examined qigong in connection with a wide range of medical conditions (including hypertension, pain, and cancer) and with respect to quality of life.
