El Capitan Granite is a type of granite (also see granodiorite), in a large area near El Capitan, in Yosemite National Park, California, United States.

The granite forms part of the Tuolumne Intrusive Suite (also known as Tuolumne Batholith), one of the four major intrusive suites within the Sierra Nevada.

[2] It is found west of Half Dome Granodiorite, both north and south, to a western limit near Cookie Cliffs.

All of Turtleback Dome, El Capitan, The Three Brothers, and Cathedral Rocks are made of El Capitan Granite[3] as is Elephant Rock.

[5] El Capitan Granite intruded older plutonic rocks about 103 Ma,[3] during the Cretaceous Period.
