The visitor fell on Wednesday near the Yavapai Geology Museum, located on the South Rim in Grand Canyon Village, according to the National Park Service.
Grand Canyon National Park rangers responded and found the human body about 400 meters below the rim. Helicopter and technical rescue teams recovered the body and the park's officials are investigating.
Last week, two people died while they were visiting the canyon.
On Thursday, a man from Hong Kong took pictures of an oversight when he slipped and fell, according to Grand Canyon West.
The man, who was in his late 50s, was part of a tour group who visited the Eagle Point observatory at the Grand Canyon West and was apparently suicidal, according to David Leibowitz, an Eagle Point spokesman.
"Every employee of the Grand Canyon West remains the thoughts and prayers of this person's close and members of the tour group," said the tourist goal in a statement.
The first of the three deaths was not the result of a case, according to Vanessa Ceja-Cervantes, a spokesman for the Grand Canyon National Park. She said the victim was a foreigner and that the body was found on March 26 in a forest area south of the South Rim Village park.
The park and Coconino County Medical Examiner are conducting a study.  "On average, there are about 12 deaths in the park per year, but a small percentage of them are from fatalities," Ceja-Cervantes says. "The causes of these deaths range from heat to drowning, to medical problems and more. High altitude plays a role in some of the deaths."
