The Sequoia and Kings Canyon National Parks is the consolidated management structure for Sequoia National Park and Kings Canyon National Park in California. The two parks have been jointly administered since 1943. They have a combined size of 1,353 square miles (3,500 km2). It was designated the UNESCO (United Nations Educational Scientific and Cultural) Sequoia-Kings Canyon Biosphere Reserve in 1976.

The parks were joined in1943. Sequoia National Park was set aside to protect the sequoia trees from logging companies in order to keep the pristine beauty of the land for years to come. It wasn't until a few months after the bill had passed that the park was given the National Park name by the Secretary of the Interior, John Willock Noble. Stewart also collaborated with John Muir, who was known for his efforts to preserve Kings Canyon National Park, in order to achieve the formation of the National Park Service.

They house various natural spectacles. The parks are a large part of the Sierra Nevada Mountain Range. The two adjacent parks extend from the foothills of the San Joaquin Valley to the crest of the Sierra Nevada and contain the highest parts of that range. Pleistocene glaciers left an abrupt topography of granite carved canyons and domes and hundreds of glacial lakes. Among the peaks is Mount Whitney which, at 14,491 feet(4.417 km) , is one of the tallest mountains in the United States. The parks house about 200 marble caves combined.
