Hohlgangsanlage 8 (often abbreviated to Ho8, also known as the German Underground Hospital or the Jersey War Tunnels) was a partially completed underground hospital complex in St. Lawrence, Jersey, built by German occupying forces during the occupation of Jersey during World War II. Over 1 km (1,100 yd) of tunnels were completed. After the liberation of the Channel Islands, the complex was converted into a museum detailing the occupation and remains a visitor attraction.
