List of highest mountain peaks in Washington

The following is a list of the highest mountain peaks in the State of Washington. All peaks are located in the Cascade Range, the largest of the mountain ranges in the state. Washington is one of only four states to have a high point reaching above 14,000 feet on Mount Rainier, the other states being Alaska, California, and Colorado.

Topographic elevation is the vertical distance above the reference geoid, a precise mathematical model of the Earth's sea level as an equipotential gravitational surface. Topographic prominence is the elevation difference between the summit and the highest or key col to a higher summit. Topographic isolation is the minimum great circle distance to a point of higher elevation.

This article defines a major mountain peak as a summit with at least 500 metres (1,640 ft) of topographic prominence and 2,700 metres (8,858 ft) of elevation. An ultra prominent peak is a summit with at least 1,500 metres (4,921 ft) of topographic prominence. Prior to its eruption in 1980, Mount St. Helens was at 9,677 ft (2,950 m), ranking number five on the list in both elevation and prominence, but is now reduced to 8,365 ft (2,550 m). Despite being far below the 2,700 meter minimum for inclusion, Mount St. Helens is the seventh highest in topographic prominence at 4,605 ft (1,404 m).

Mount Rainier is the highest mountain in Washington state.

Mount Adams is the second highest mountain in the state.

Mount Baker is the third highest mountain in the state.

Glacier Peak is the fourth highest mountain in the state.
