Robert Dean Silva Burnquist, better known as Bob Burnquist, is a professional skateboarder. The biggest competition that he has won was the vert contest at the 2001 X-Games. Before his final run- the last run of the event- Burnquist was sitting in second place behind two-time defending champion Bucky Lasek. Burnquist produced a flawless run on the skate ramp, including multiple tricks that had never been seen before, and as a result, were unnamed. During the run, commentator Tony Hawk went hoarse and nearly lost his voice while screaming in disbelief. Burnquist was rewarded with a 98, the highest score ever given in skateboard vert. Burnquist's speciality is switch stance skateboarding. He has always tried to find new ways to make his tricks more creative and more difficult. He has a signature trick called "one-footed smith grind".

Burnquist has also been featured in the hit video game, Tony Hawk's Pro Skater, and appeared in all of its sequels with the exception of Pro Skater 3 due to license restrictions as a result of appearing in another skating game, X-Games Skateboarding, during that year. He returned as a featured character in the series starting again with Tony Hawk's Pro Skater 4 and has since appeared in all the series games following that. Burnquist has also won a gold medal on the 2005 X-Games Best Trick vert contest. Burnquist is the only skater to go over a loop ramp with a gap in it (OP King Of Skate) Not only was the loop gapped, but Bob also did the gap switch. He is also the first skater to go through a loop while riding switch stance, and the first to go all the way around a full pipe just by pumping up to speed inside it. In 2000, Burnquist won the X-Games' best trick contest with his famous fakie 5-0, fakie Kickflip out off of the grind bar. Bob Burnquist completed a BASE jump after attempting a world class rail slide into the Grand Canyon. The first attempt nearly cost Burnquist his life after he missed the rail and fell out of control before regaining himself and successfully deploying his parachute. After some adjustments to the take-off skate ramp his second attempt went off flawlessly. This stunt was shown in an episode of the television show Stunt Junkies.

Burnquist's latest addition to his backyard skate-park is one of the world's few permanent Mega Skate Ramp. He had also started the Bob Burnquist Foundation to bring knowledge about organic farming and gardening to schools, and was one of the founders of the Action Sports Environmental Coalition, a nonprofit organization that brings ecological awareness to skateboarders, surfers and BMXers.
