John Harvey Butchart (May 10, 1907 – May 29, 2002) was an American hiker and mathematican who was well known for his exploits in and around the Grand Canyon in Arizona, United States.

In multiple trips over several years, he had completed the first route from one end of the national park to the other, except for about four miles below Great Thumb and Tahuta Points.

[6]: 56  [1]: 195 Colin Fletcher relied heavily on Butchart's knowledge to plan his own hike through the whole park in a single journey later that year.

[6] Fletcher wrote: Beginning in 1970, Butchart published three slim volumes of trail notes from his exploration records.

[1] Butchart's famously cryptic texts were written for those developing the strength and skill to hike safely in the most remote areas.

[4] The collection includes more than 1,000 pages of his original trail logs, 52 hiking maps with handwritten annotations, more than 7,000 color slide photographs, extensive correspondence, and related publications.

It is 1.5 miles west of Gunther Castle along the divide between Kwagunt and Chuar Valleys but not specifically mentioned in his route guides.
