Mount Le Conte (or LeConte) is a mountain located in the Sierra Nevada of California.

The boundary between Inyo and Tulare counties runs along the crest of the Sierra, across Mount Le Conte.

The mountain was named in 1895 for Joseph Le Conte (1823–1901), the first professor of geology and natural history at the University of California.

The southwest side of Mount Le Conte drains into Rock Creek, thence into the Kern River, which ends in the Central Valley of California.

The east side of Le Conte drains into Tuttle Creek, and thence into Diaz Lake in the Owens Valley.
