Rocky Butte is an extinct volcanic cinder cone butte in Portland, Oregon, United States. It is one of four, along with Kelly Butte, Powell Butte, and Mount Tabor, inside the city that are each home to a city park, Rocky Butte playing host to Joseph Wood Hill Park. A rotating beacon at the summit of the butte is visible for miles. It is also part of the Boring Lava Field, a group of over 30 cinder cones in Oregon and Washington. The slopes of Rocky Butte are also home of the Rocky Butte Natural Area. In addition, it was formerly home to a jail and Judson Baptist College. Currently it is the location of a City Bible Church campus, Portland Bible College and City Christian Schools.
