Street luge is an extreme gravity-powered activity that involves riding a streetluge board (sometimes referred to as a sled) down a paved road or course. Street luge is also known as land luge or road luge. Like skateboarding, street luge is often done for sport and for recreation.

Other than the supine riding position and very high speeds (40-97 mph / 64-157 km/h), street luge has little relation to its winter namesake (luge).

Street luge was born in Southern California as downhill skateboarders found they could reach faster speeds by lying down on their skateboards. This early form of the sport is now referred to as "classic style" or "butt boarding".

In 1975, the first professional race was held at Signal Hill, California, and hosted by the U.S. Skateboard Association. The race winner was based on top speed. The boards used in this race varied from basic skateboards to complex skate cars in which the rider was completely enclosed by plastic or fiberglass. The sport was not commonly referred to as street luge at this time but the term luge was used to describe some participants' riding position. Most contestants were standing up; however, an opening in the rules enabled riders to choose their own board position, including supine. By 1978, repeated injuries to both riders and spectators halted the races at Signal Hill.
