浅滩冲浪（Skimboarding），又称沙板，是在沙滩浅水区域从事类似冲浪技巧的运动，或者也可以解释沙滩和板类运动的结合。就像其他许多水上板类运动一样（冲浪、滑水、风浪板、风筝冲浪、划桨冲浪…等），浅滩冲浪这项运动是由浅水区域的沙滩、以及水上运动玩家与沙板所组成的一项运动，当然这活动绝对是属于水上板类运动的其中一种，跟其他水上板类运动一样初期所使用的板子都为木板所制作的，现在多数看到的沙板外观较为类似冲浪板，但和冲浪板相比较下，却又比冲浪板短小且轻薄，也没有冲浪板拥有的尾舵和脚绳，浅滩冲浪的玩法有部分类似冲浪也有些却类似滑板，比较像似冲浪与滑板的结合，玩家需将板子丢在沙滩上浅水区域，运用助跑赋予的速度使板子前进，借此上板顺着浅滩的水面滑行出去，享受骑乘在沙板上所带来的凌驾感乐趣。

Skimboarding (or skimming) is a boardsport in which a skimboard (much like a surfboard but smaller and without fins) is used to glide across the water's surface to meet an incoming breaking wave, and ride it back to shore. Wave-riding skimboarders perform a variety of surface and air maneuvers, at various stages of their ride, out to, and back with, the wave. Some of these are known as "wraps," "big spins," "360 shove-its" and "180s." Unlike surfing, skimboarding begins on the beach by dropping the board onto the thin wash of previous waves. Skimboarders use their momentum to skim out to breaking waves, which they then catch back into shore in a manner similar to surfing. Another aspect of skimboarding is "flatland," which involves performing tricks derived from skateboarding such as ollies and shove-its on the wash of waves without catching shore breaks. Skimboarding originated in Southern California when Laguna Beach lifeguards wanted to surf the local shorebreak that was too fast and shallow for surfboards. Skimboarding has developed since then to ride waves much like surfing, performing aerial maneuvers and pulling into the barrel of the wave.
