China Hat is a volcanic butte on the southeastern flank of Newberry Volcano in Deschutes County, Oregon, United States . It is a rhyolitic dome dating from the age of the Middle Pleistocene.[2] Both China Hat and nearby East Butte are covered by Mazama Ash and Newberry Ash.[3]

Although China Hat is often thought of as a side vent of Newberry Volcano less than ten miles away,[4] it is estimated to be older than first formation of the Newberry Caldera, 780,000 thousand years old [5] versus 500,000 years ago [6] and is on the western edge of a series of high lava plains eruptions derived from a tongue of the same mantle plume that fuels the Yellowstone Caldera[7]

China Hat Road, named after the butte, starts in Bend and heads to Fort Rock.[8] The road is a hotspot for law enforcement.[8] China Hat Campground is a campground located near China Hat butte along this road.[9]

The butte was named for its similarity in appearance, when viewed from Fort Rock, to the Asian conical hat worn by Chinese immigrant laborers.[8]
