糖玻璃（Sugar glass或candy glass），并非玻璃，而是电影、电视剧拍摄或剧场演出中用作替代玻璃的道具。正如名称所言，这种玻璃是用糖类物质制作的。

在戏剧中，为了表现打斗的激烈，往往有人被抛出，撞碎玻璃，用玻璃瓶打人或抛掷玻璃器皿等场面，而使用真正的玻璃，会对演员造成意外伤害，糖玻璃正是由此出现。

糖玻璃成分主要是糖、玉米糖浆和水。在原料成型放干之后，外观酷似玻璃。尽管如此，破碎的糖玻璃仍然可能对演员造成一定伤害。干燥后的糖玻璃必须马上用于拍摄，否则糖玻璃会逐渐变软变黏。

Sugar glass (also called candy glass, edible glass, and breakaway glass) is a brittle transparent form of sugar used to simulate glass in movies, photographs and plays. It is much less likely to cause injuries than real glass, and it easily breaks convincingly, making it an excellent choice for stunts. Sugar glass is also used to make sugar sculptures. Because sugar glass is hygroscopic, it must be used soon after preparation, or it will soften and lose its brittle quality.
