Mount Darwin is a flat-topped mountain in the Sierra Nevada, on the border of between Fresno and Inyo counties in Kings Canyon National Park and the John Muir Wilderness of California.

Theodore Seixas Solomons (1870–1947) was an American explorer and early member of the Sierra Club. From 1892 to 1897 he explored and named the Mount Goddard, Evolution Valley and Evolution Basin region in what is now northern Kings Canyon National Park in eastern California. He was instrumental in envisioning, exploring, and establishing the route of what became the John Muir Trail from Yosemite Valley along the crest of the Sierra Nevada to Mount Whitney
