The Wappo (endonym: Micewal[4]) are an Indigenous people of northern California.

[5] Prior to European colonization, the Wappo lived by hunting and gathering, and lived in small groups without centralized political authority, in homes built from branches, leaves and mud.

When Mexicans arrived to colonize California, Wappo villages existed near the present-day towns of Yountville, St. Helena and Calistoga.

Those on the south shore of Clear Lake were completely absorbed and dispersed to the Spanish missions in California.

[6] The name Wappo is an Americanization of the Spanish term guapo, which means, among other things, "brave."
