A sleep-related breathing disorder is a sleep disorder in which abnormalities in breathing occur during sleep which may or may not be present while awake. According to the International Classification of Sleep Disorders, sleep-related breathing disorders are classified as follows:

• Sleep apnea, including the more specific disorders of obstructive sleep apnea and central sleep apnea
• Central hypoventilation syndromes
• Obesity hypoventilation syndrome
• Sleep-related hypoxemia disorder
• Sleep-related hypoventilation due to a medication or substance, or due to a medical disorder

There are many different surgical procedures for sleep-related breathing disorders, sometimes collectively termed "sleep surgery".
