Alfentanil (trade name) is a parenteral short-acting synthetic opioid analgesic drug, used for anaesthesia in surgery. Alfentanil was discovered at Janssen Pharmaceutica in 1976.

Alfentanil is useful for: short operative analgesia, e.g. outpatient and day surger; enhancement of general anaesthesia; suppression of spontaneous respiration in patients on assisted ventilation; cardiovascular surgery; it disrupts this system relatively little.

The key side effect is that of severe respiratory depression.
