A euthanasia device is a machine engineered to allow an individual to die quickly with minimal pain. The most common devices are those designed to help terminally ill people die by voluntary euthanasia or assisted suicide without prolonged pain. They may be operated by a second party, such as a physician, or by the person wishing to die. There is an ongoing debate on the ethics of euthanasia and the use of euthanasia devices.

Assisted suicide – sometimes referred to as medical aid in dying – means a procedure in which people take medications to end their own lives with the help of others, usually medical professionals. The term usually refers to physician-assisted suicide (PAS), which is an end of life measure for a person suffering a painful, terminal illness. Once it is determined that the person's situation qualifies under the physician-assisted suicide laws for that location, the physician's assistance is usually limited to writing a prescription for a lethal dose of drugs.
