Dark tourism (also Thana tourism, black tourism, morbid tourism or grief tourism) has been defined as tourism involving travel to places historically associated with death and tragedy. The main attraction to dark locations is their historical value rather than their associations with death and suffering. Holocaust tourism contains aspects of both dark tourism and heritage tourism. Dark tourism deals with the philosophical interrogation on death.

Destinations of dark tourism include castles and battlefields such as Culloden in Scotland and Bran Castle and Poienari Castle in Romania; former prisons such as Beaumaris Prison in Anglesey, Wales and the Jack the Ripper exhibition in the London Dungeon; sites of natural disasters or man made disasters, such as Hiroshima Peace Memorial Park in Japan, Chernobyl in Ukraine and the commercial activity at Ground Zero in New York one year after September 11, 2001.

It also includes sites of human atrocities and genocide, such as the Auschwitz concentration camp in Poland, the Nanjing Massacre Memorial Hall in China, the Tuol Sleng Genocide Museum in Cambodia; the sites of the Jeju Uprising in South Korea and the Spirit Lake Internment Camp Centre near La Ferme, Quebec as an example of Canada's internment operations of 1914–1920.
