The 1860 Wiyot Massacre refers to the incidents on February 26, 1860 on Indian Island, near Eureka, California. Approximately 100 Wiyot men, women, and children were attacked by European immigrants who had settled in area within the previous 10 years as part of the California Gold Rush. In order to avoid attention from Eureka, the attackers only used hatchets, clubs and knives.

The island was abandoned after the attack. Recently, the Wiyot have been repurchasing the land in order to perform their annual "world renewal ceremony".^[1]
