醋托啡（英文：Acetorphine），是一种镇痛剂药物，其药效大概等于同质量吗啡的8700倍。

Acetorphine is a potent opioid analgesic, up to 8700 times stronger than morphine by weight. It is a derivative of the more well-known opioid etorphine, which is used as a very potent veterinary painkiller and anesthetic medication, primarily for the sedation of large animals such as elephants, giraffes and rhinos.
