Skateboarding is the act of riding on and performing tricks with a skateboard. A person who skateboards is referred to as a skateboarder or skater.

Skateboarding is a recreational activity, a job, or a method of transportation. Skateboarding has been shaped and influenced by many skateboarders throughout the years. A 2002 report by American Sports Data found that there were 18.5 million skateboarders in the world. Eighty-five percent of skateboarders polled who had used a board in the last year were under the age of 18, and 74 percent were male.

Skateboarding is relatively modern. A key skateboarding trick, the ollie, was only developed in the late 1970s. This ollie was used only on vertical ramps on flat ground. A decade later, freestyle skateboarder Rodney Mullen invented the flat ground ollie as well as the kickflip.
