This article comprises three sortable tables of major mountain peaks^[a] of the U.S. State of California.

The summit of a mountain or hill may be measured in three principal ways:

1. The topographic elevation of a summit measures the height of the summit above a geodetic sea level.^[b][c] The first table below ranks the 50 highest major summits of California by elevation.
2. The topographic prominence of a summit is a measure of how high the summit rises above its surroundings.^[d][c] The second table below ranks the 50 most prominent summits of California.
3. The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation.^[e] The third table below ranks the 50 most isolated major summits of California.

Highest major summits

Of the highest major summits of California, 16 peaks exceed 4000 meters (13,123 feet) elevation and 46 peaks exceed 3000 meters (9843 feet) elevation.

Most prominent summits

Of the most prominent summits of California, only Mount Whitney exceeds 3000 meters (9843 feet) of topographic prominence. Five peaks exceed 2000 meters (6562 feet), nine peaks are ultra-prominent summits with more than 1500 meters (4921 feet), and 35 peaks exceed 1000 meters (3281 feet) of topographic prominence.
