Today, Mount St. Helens is the 35th highest major summit of the state.

This article comprises three sortable tables of major mountain peaks of the U.S. State of Washington.

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. The first table below ranks the 100 highest major summits of Washington by elevation.
2. The topographic prominence of a summit is a measure of how high the summit rises above its surroundings. The second table below ranks the 50 most prominent summits of Washington.
3. The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation. The third table below ranks the 25 most isolated major summits of Washington.

Highest major summits

Of the major summits of the State of Washington, Mount Rainier exceeds elevation, four peaks exceed elevation, and 97 peaks exceed elevation.
