Mount Farquhar, Mountain summit in Tulare County, California

Mount Farquhar is a 3,870-metre peak on the Great Western Divide in Kings Canyon National Park, Tulare County, California, rising 143 metres above the surrounding terrain. Its west slopes feed Sphinx Creek, while its east slopes drain into Cross Creek and North Guard Creek. The summit lies 1.6 km south-west of North Guard.

The summit was officially named in 1989 to honor conservationist Francis P. Farquhar, who played a key role in establishing Kings Canyon National Park. It was previously known as Notch Peak.

The first ascent, on 17 July 1932, was made by a party of fourteen climbers via the South Ridge, among them Norman Clyde, Glen Dawson and Dorothy Baird. They scrambled cross country to the Sphinx Lakes, gained the col south of the peak and followed the ridge to the top. The peak was called Notch Peak until 1989, after the notch visible in its profile from the east.

Climbers access the summit via multiple established routes including the Northwest Ridge and Northeast Face. The easiest paths are classified as class 3 scrambles, requiring basic mountaineering experience.

The mountain's west-facing slopes feed Sphinx Creek, while its east-facing slopes drain into Cross Creek and North Guard Creek. These creek systems eventually flow through Bubbs Creek toward the Kings River.
