Kaupulehu or Kaʻūpūlehu is the site of a historic settlement on the west coast of Hawaiʻi island, the largest of the Hawaiian Islands. Devastated by a lava flow, the area is now the home of luxury hotels such as the Four Seasons Resort Hualalai.
Kaʻūpūlehu is located in the northern part of the Kona district. The name comes from Ka ʻulu pūlehu which means "the roasted breadfruit" in the Hawaiian language. Access is from the lower Hawaii Belt Road, known as Route 19 or Queen Kaʻahumanu Highway. In 1800, the Volcano Hualālai erupted and the resulting lava flow reached the sea near Kaʻūpūlehu. Oral histories tell of a bay and fishponds that were destroyed. The flow is named after Kaʻūpūlehu. The crater on the side of Hualālai resulting from the eruption is also given the name Kaʻūpūlehu, located at about 6,000 feet (1,800 m) elevation.
