The Tuolumne River [ tu ː ɒləmi ɹɪvɚ ] is a river in the U.S. state of California. The river rises in Yosemite National Park, near the Tioga Pass in the Sierra Nevada and flows almost parallel to the Merced River to the west. After about 250 km it flows into the San Joaquin River. The largest city on the river is Modesto.

In the upper part of the river it crosses the Tuolumne Meadows and the Grand Canyon of the Tuolumne River. Below that it is jammed in the Hetch Hetchy Valley. Outside of Yosemite National Park, it unites with the tributaries of the Middle Fork Tuolumne River and South Fork Tuolumne River.
