A gurney, known as a trolley in British medical context, is the U.S. term for a type of stretcher used in modern hospitals and ambulances in developed areas. A hospital gurney is a kind of narrow bed on a wheeled frame which may be adjustable in height. For ambulances, a collapsible gurney is a type of stretcher on a variable-height wheeled frame. It is usually covered with a disposable sheet to aid in preventing infections. Its key value is to facilitate moving the patient and sheet onto a fixed bed or table on arrival at the emergency room. Both types may have straps to secure the patient.

The name gurney comes from its similarity to a horse-drawn cab patented in the U.S. in 1883 by J. Theodore Gurney. Advanced models of collapsible gurneys have a lower frame that can fold up on contact with the rear deck of the ambulance, and have a securing device that mates with a counterpart inside the ambulance to keep it from moving during transport. Shelves, hooks and poles for medical equipment and intravenous medication are also frequently included.

Gurneys in hospitals come in two types:

1. Non-power assisted: Totally manually powered.
2. Power assisted: Uses a small motor to help amplify the push energy. Usually used in bariatrics departments with heavy patients.
