Fin Dome is an 11,673-foot-elevation (3,558-meter) granite summit located 1.5 mile west of the crest of the Sierra Nevada mountain range, in the southeast corner of Fresno County, in northern California.

[3] It is situated in the Rae Lakes area of Kings Canyon National Park, approximately 15.5 miles (24.9 km) west of the community of Independence.

Topographic relief is significant as the east aspect rises 1,135 feet (346 meters) above Rae Lakes in one-quarter mile.

This geographical feature was named by Bolton Brown in 1899 when he explored the lake basin in its vicinity, because it resembled the fin of a sea serpent.

As fronts approach, they are forced upward by the peaks, causing them to drop their moisture in the form of rain or snowfall onto the range (orographic lift).
