Sandboarding is a boardsport and extreme sport similar to snowboarding that involves riding down a sand dune while standing on a board, with both feet strapped in. Sand sledding can also be practised sitting down or lying on the belly or the back. It typically involves a sand sled, although it is also somewhat possible to use snow sleds or snowboards. The invention of modern sandboarding is largely attributed to Lon Beale, aka 'Doctor Dune', who began sandboarding in 1972 in California's Mojave Desert. Sandboarding has adherents throughout the world, but is most prevalent in desert areas or coastal areas with beach dunes. It is less popular than snowboarding, partly because it is very difficult to build a mechanised ski lift on a sand dune, meaning participants must climb or ride a dune buggy or all-terrain vehicle back to the top of the dune. On the other hand, dunes are normally available year-round as opposed to ski resorts, which are seasonal.

The sandboard base is much harder than a snowboard, and is built mostly out of formica or laminex with special base materials now being made, that will slide on wet and dry sand. To glide in the sand, the board bottom is often waxed, usually with a paraffin-based sandboard wax, before a run. Afterwards, the bottom of the board may have a lightly sanded look to it. Most terrain sandboards are composed of hardwood ply, while 'full-size' sandboards are a wood, fiber glass, and plastic composite. However, a snowboarding base will sometimes work on steeper dunes as well.

Sandboarding is practised worldwide, with locations available on every continent except Antarctica. The World's Greatest Sandboarding Destinations lists sandboarding destinations in over 65 territories.

Drorbamidbar has sandboarding in Israel at Negev Desert not far from Ashalim in Ramat HaNegev.

Little Sahara on Kangaroo Island in South Australia is a sand dune system roughly covering two square kilometres (0.77 sq mi). The highest dune is approximately 70 metres (230 ft) above sea level.

Lucky Bay, about 30 kilometres (19 mi) south of Kalbarri, in Western Australia, is another sandboarding hotspot. Sandboarding Tours are offered in the area.

The Stockton dunes, 2.3 hours north from Sydney. Stockton Bight Sand Dunes system is up to one kilometre (0.62 mi), 32 kilometres (20 mi) long, and covers an area of over 4,200 hectares (10,000 acres; 42,000,000 m²). The massive sand dunes climb up to 40 metres (130 ft) high. Located only minutes from the centre of Nelson Bay, it is the largest sand dune system in Australia.
