Double Rainbow was a viral video filmed by Paul "Bear" Vasquez (September 5, 1962 – May 9, 2020). The clip, filmed in his front yard just outside Yosemite National Park, in the U.S. state of California, shows his ecstatic reaction to a double rainbow. As of August 2022, Vasquez's video had accumulated more than 50 million views on YouTube.

Vasquez was a native of East Los Angeles, where he served as a Los Angeles County firefighter. After two years, he re-settled in Yosemite in 1985, eventually buying an eight-acre (3.2 ha) plot. He was married with two children, before divorcing, becoming a truck driver, and participating in a single mixed martial arts bout.

Vasquez lived in a mobile farm outside Mariposa, California, approximately 10 miles (16 km) from Yosemite, where he operated a farm and uploaded occasional videos of his life.

In a May 3, 2020 Facebook post, Vasquez spoke of feeling feverish and having trouble breathing. However, he refrained from going to a hospital, as he looked forward to reincarnating and "enjoying the ride". On May 9, Vasquez died in the emergency room of John C. Fremont Hospital in Mariposa, California. Vasquez was tested for COVID-19 but no results have yet been released.
