Kohala, Shield volcano in Hawaii County, United States.

Kohala is an extinct shield volcano on the northeastern side of Hawaii Island, the oldest of the island's five volcanoes. It rises to 1,670 meters and covers 606 square kilometers, just under 6% of the island. Its broad summit forms a nearly level crest, and its slopes are cut by deep erosion gorges. A massive landslide 250,000–300,000 years ago removed its northeast flank, giving the mountain a foot-like shape.

This volcano began forming roughly one million years ago, with its last eruption occurring around 120,000 years ago. This makes it the oldest of the volcanoes that make up Hawaii Island.

Kohala gives its name to the northern districts of North and South Kohala, and North Kohala is the birthplace of King Kamehameha I, near Hawi. Sweet potato has been cultivated on the volcano's leeward slopes for centuries, a crop still tied to the area's farming life.

Kohala is an extinct volcano with no maintained summit trail, so there is no route to the 1,670 m top; the windward sea cliffs of the northeast shoreline are the clearest mark of the ancient landslide. The mountain lies in Hawaii County, and the northern districts of North and South Kohala take its name. Access is by road through the surrounding ranch land.

Marine fossils found on the volcano's slopes hint at a massive tsunami that struck around 120,000 years ago. These traces show how ancient natural forces reshaped the volcanic structure.
