Jump-off Joe was a 100-foot-tall sea stack geological formation composed of middle Miocene concretionary sandstone at Nye Beach in Newport, Oregon, United States. It was a well-known tourist attraction before World War I. It formed sometime before the 1880s when it was connected to the mainland, and was a major impediment walking the beach. Early travelers would have to jump off the side to get over it, hence the name. Early writers claimed the site was connected with Native American mythology.
