Green Lake (Hawaiian: Ka Wai o Pele) was a freshwater crater lake in Puʻu Kapoho crater on the island of Hawaiʻi.
With a surface area of 0.8 hectares (2.0 acres) and a maximum depth of 61 metres (200 ft), it was the largest natural freshwater lake in the Hawaiian Islands, and, along with Lake Waiau, was one of two freshwater lakes on Hawaiʻi Island.

Hawaiian myths state that the lake was the first place visited by Pele, the volcano deity.
The lake was a popular swimming spot for locals and tourists.
Extensive vegetation, mainly Hibiscus tiliaceus, overhung the lake, shading about twenty percent of the lake's surface.

On June 2, 2018, the lake was destroyed when lava flows from Kīlauea's lower Puna eruption boiled it away and completely filled the entire basin.
