Derek Humphry is a British-born American journalist and author notable as a proponent of legal assisted suicide and the right to die. In 1980, he co-founded the Hemlock Society and, in 2004, after that organization dissolved, he co-founded Final Exit Network. From 1988 to 1990, he was president of the World Federation of Right to Die Societies and is the current president of the Euthanasia Research & Guidance Organization (ERGO).

The right to die is a concept based on the opinion that human beings are entitled to end their life or undergo voluntary euthanasia. Possession of the right to die is often bestowed with the understanding that a person with a terminal illness, incurable pain, or without the will to continue living should be allowed to end their own life, use assisted suicide, or decline life-prolonging treatment. The question of who, if anyone, may be empowered to make this decision is often the subject of debate.
