58 people have accidentally fallen into the Grand Canyon and died between 1925 and 2005. 48 others died while hiking inside the canyon. A quarter of the deaths are because of heat exhaustion. There also has been suicides but I'm not sure how many.
Since the canyon became a national park in 1919, the number is 653 people -- but not all of them died in the park, because the canyon extends well beyond the park boundaries to the Navajo, Havasupai and Hualapai Indian reservations and Lake Mead Recreational Area.
